工程流体力学英语Engineering Fluid MechanicsThe study of fluid mechanics is a fundamental aspect of engineering, as it underpins the design and analysis of a wide range of systems and devices. Fluid mechanics encompasses the behavior of liquids and gases, and its principles are essential in fields such as aeronautics, mechanical engineering, civil engineering, and chemical engineering.One of the primary areas of focus in fluid mechanics is the concept of fluid flow. This includes the study of the properties of fluids, such as density, viscosity, and compressibility, as well as the forces acting on them. Fluid flow can be classified into two main types: laminar flow, where the fluid particles move in parallel layers, and turbulent flow, where the fluid particles move in a chaotic, unpredictable manner.Understanding the behavior of fluids in both laminar and turbulent flow is crucial for various engineering applications. For example, in the design of aircraft wings, the study of fluid mechanics is essential to determine the lift and drag forces acting on the wing, which inturn influences the aircraft's performance and efficiency. Similarly, in the design of hydraulic systems, such as pumps and valves, fluid mechanics principles are used to ensure the optimal flow of fluids and the minimization of energy losses.Another important aspect of fluid mechanics is the study of pressure and buoyancy. Pressure, which is the force exerted by a fluid on a surface, plays a crucial role in the design of structures, such as dams and pipelines, as well as in the operation of various devices, such as hydraulic brakes and pneumatic systems. Buoyancy, on the other hand, is the upward force exerted by a fluid on an object immersed in it, and it is a fundamental principle in the design of ships, submarines, and other floating structures.In addition to these fundamental concepts, fluid mechanics also encompasses the study of more complex phenomena, such as boundary layer theory, which describes the behavior of fluids near solid surfaces, and computational fluid dynamics (CFD), which involves the use of computer simulations to model and analyze fluid flow.The application of fluid mechanics principles is not limited to the design and analysis of engineering systems. It also plays a crucial role in various natural phenomena, such as the movement of air and water, the formation of weather patterns, and the behavior ofbiological systems, such as the circulatory system in the human body.Overall, the study of engineering fluid mechanics is a vast and complex field, with numerous applications across a wide range of industries. As technology continues to evolve, the importance of fluid mechanics in engineering design and analysis will only continue to grow, making it an essential subject for students and professionals alike.。

拉格朗日力学英文Lagrangian MechanicsLagrangian mechanics is a formulation of classical mechanics that describes the motion of a system in terms of a function called the Lagrangian which is the difference between the kinetic and potential energies of the system. This approach provides a powerful and elegant way to derive the equations of motion for a wide range of physical systems, from simple pendulums to complex multi-body systems.The foundation of Lagrangian mechanics is the principle of stationary action which states that the motion of a system will follow the path that minimizes the action integral over the time interval of interest. This principle can be used to derive the Euler-Lagrange equations which are a set of second-order differential equations that describe the motion of the system. The Lagrangian function is defined as the difference between the kinetic energy and the potential energy of the system, and the Euler-Lagrange equations relate the Lagrangian function to the forces acting on the system.One of the key advantages of Lagrangian mechanics is its ability tohandle systems with constraints. Constraints are restrictions on the motion of the system, such as the motion of a pendulum being restricted to a circular path. In Lagrangian mechanics, these constraints are incorporated into the Lagrangian function, and the Euler-Lagrange equations automatically take them into account. This makes Lagrangian mechanics particularly useful for analyzing complex systems with multiple degrees of freedom and complicated constraints.Another advantage of Lagrangian mechanics is its ability to handle non-conservative forces, such as friction or damping. These forces can be incorporated into the Lagrangian function through the use of generalized coordinates and the principle of virtual work. This allows for the analysis of a wide range of physical systems, including those with dissipative forces.Lagrangian mechanics also provides a powerful tool for analyzing the symmetries of a system. Symmetries in the Lagrangian function can lead to conserved quantities, such as momentum or angular momentum, which can simplify the analysis of the system's motion. This is particularly useful in fields such as particle physics, where the underlying symmetries of the system play a crucial role in determining the behavior of the particles.The formulation of Lagrangian mechanics was developed by theFrench mathematician Joseph-Louis Lagrange in the late 18th century. Lagrange's work built upon the earlier work of Euler and Hamilton, and it provided a more general and unified framework for describing the motion of mechanical systems. Lagrangian mechanics has since become a fundamental tool in the study of classical mechanics and has been extended to other areas of physics, such as field theory and quantum mechanics.In Lagrangian mechanics, the motion of a system is described by a set of generalized coordinates which can be any set of independent variables that uniquely specify the configuration of the system. The Lagrangian function is then defined in terms of these generalized coordinates and their time derivatives. The Euler-Lagrange equations are then used to derive the equations of motion for the system, which can be solved to determine the trajectory of the system over time.One of the key applications of Lagrangian mechanics is in the analysis of multi-body systems, such as the motion of planets in the solar system or the motion of robots with multiple joints. In these systems, the Lagrangian function can be used to derive the equations of motion for the entire system, taking into account the interactions between the various components. This makes Lagrangian mechanics a powerful tool for the design and analysis of complex mechanical systems.Another important application of Lagrangian mechanics is in the field of control theory, where it is used to design control systems that can manipulate the motion of a system in a desired way. By using the Lagrangian function to describe the system's dynamics, control engineers can develop control algorithms that can efficiently and effectively control the motion of the system.Overall, Lagrangian mechanics is a powerful and versatile approach to the study of classical mechanics that has had a profound impact on the field of physics and engineering. Its ability to handle complex systems with constraints and non-conservative forces, as well as its connection to symmetries and conserved quantities, make it a essential tool in the study of a wide range of physical phenomena.。

Students may drop this classfrom now until September 15 without “W” grade assigned.Important Dates:Midterm examination dates: October 11 and November 15Final exam date: Tuesday, December 19, 0715-0930Term project report submission date: Nov. 29Reserve Desk:The Reserve Desk is located by the book checkout area in the ClarkLibrary. To help your study in the course material, the instructor hasreserved some reference books, technical articles, and supplemental lecturenotes.Homework: Work the homework problems on one side of a sheet of paper only. Youneed to number all the pages if more than one page is submitted. On top ofeach page write down your name, the course number, the semester, and thesubmission date. List the problem numbers in the Dowling textbook andrestate the statement of the problem including simple sketches, ifapplicable. Show your working steps and circle the numeric solutions. It isvery important to have one or two sentences describing your conclusions.This is a brief statement used to state the physical significance orimplication of your answer. Underline them and don’t forget units! Theinstructor will pay additional attention to this requirement. The homeworkassignments are collected in class on Sept. 25, Oct. 23, and Nov. 20. Nolate assignments will be accepted, as the problem solutions will be postedimmediately after the class due date.Laboratory: A Laboratory Activity Logbook will be purchased and kept by eachstudent. It must be brought to be checked and initialed by the instructorbefore beginning the first lab exercise. The logbook must be 8 1/2 x 11inches, NOT spiral bound. You will use it to record a detailed log of all labactivities, data, sketches of experimental setups and results, and records ofreferences used for class projects. Mark it clearly on the cover with yourname, group number, class and section, instructor, and semester. Eachpage should be numbered and dated and each lab activity labeled.Record your partners’ names, phone numbers, and schedules inside thecover.Term Project: A Term Project must be completed. The term project will involve amaterial's testing activity, which you design, initiate, and conduct in agroup (not more than three members) and must be supported by costanalysis, technical drawings, and related references. A few topics will bediscussed in class at a later date. Completed term project reports will befrom 10 pages in length, double spaced not including illustrations orappendices, and will follow the class format. A writing format will beprovided at a later date. An oral presentation on the term project must beconducted in the end of class (November 27).A group's oral presentation on the term project is expected to last at least20 minutes, followed by a 5-minute discussion period. All members of agroup project must present together, but are graded separately. Thepresentation should be technical and include view graphs or visual aidsrelated to the chosen subject area. Transparencies, films, LCD projector,and/or VCR recordings (VHS) can be used, but may not replace spokenreporting. A guideline with tips of presentation requirements will bedistributed at a later date.Mat E 195 Course Activity OutlineFinal Examination on Tuesday, December 19th from 0715 to 0930 hoursWeek StartingDate Reading: Chapter #Homework AssignmentsLaboratory1 Aug. 28 Ch.1 IntroductionProb. 1.1, 1.3, and 1.5 Lab Tour/Safety 2 Sept. 4 Labor Day --No Class on Sept. 4 Prob. 5.2, 5.5, 5.10Types of Material Failure3Sept. 11Ch.5 Stress-Strain Relationships Prob. 5.20, 5.22, 5.23 Tension Tests 4 Sept. 18Ch.5 Stress-Strain RelationshipsCh. 4 Mechanical Testing (Tension Test)Prob. 5.26, 5.30, 5.32 Mechanical Tests(Impact, Izod,Hardness, etc.) 5 Sept. 25 Ch. 4 Mechanical Testing (Tension Test)Prob. 4.4, 4.5, 4.7Problem Solving6 Oct. 2 Ch. 4 Mechanical Testing (Other Tests)Prob. 4.16, 4.18, 4.28 DMA 7 Oct. 9 Ch. 4 Mechanical Testing (Other Tests)Prob. 4.31, 4. 34, 4.37, 4.38 Exam 1 – Oct.11 8 Oct. 16 Ch.6 Complex and Principal States of Stress and StrainProb. 6.1, 6.7, 6.10Mohr’s Circles/ Term project9 Oct. 23 Ch.6 Complex and Principal States of Stress and Strain Prob. 6.14, 6.16, 6.28 SEM Fractography 10 Oct. 30 Ch. 8 Fracture of Cracked MembersProb. 8.3, 8.4, 8.7 2024-TT6 Aluminum 11 Nov. 6 Ch. 9 Fatigue of Materials Prob. 9.6, 9.7, 9.14 Fatigue Test 12 Nov. 13 Ch. 9 Fatigue of Materials Prob. 9.16, 9.20 Exam 2 –Nov. 15 13 Nov. 20 Ch. 11 Fatigue Crack Growth Prob. 11.4, 11.8, 11.13Polymers/Composites 14 Nov. 27 Ch. 12 Plastic DeformationBehavior and Models for Materials Prob. 12.1, 12.13 Term Paper Due (Nov. 29) 15 Dec. 4 Ch. 15 Time-Dependent Behavior: Creep and Damping Prob. 15.2, 15.6, 15.16 Problem Solving 16Dec. 11Review of the CourseLast Day of InstructionMatE 195 Course Learning ObjectivesUpon the completion of this course, the student will be able to:1.
