Mech 24 Statics, Kinematics and Kinetics. Prerequisites: Math 21, Phys 3. It is the aim of this course to acquaint the student of engineering with the fundamental laws, principles, and methods of mechanics, and to develop in him the ability to apply them in the solution of a great variety of problems of practical importance to the engineer. The principal topics included in this course are: Statics--Composition and resolution of forces and couples; equilibrium; analysis of simple frameworks; the laws of friction with general applications, and special reference to journal, belt and pivot friction. Kinematics--linear and angular displacement, velocity, and acceleration; rectilinear and curvilinear motion; motion curves; relative motion; motion of rigid bodies. Kinetics--Newton’s laws applied to the motion of a particle; D’Alembert’s principle; motion of the mass-center; translation, rotation and plane motion of a rigid body; work, power, energy, impulse, and momentum; principles of work and energy, principles of impulse and momentum, and their application to special types of motion of rigid bodies. _Texts: Seely and Ensign, “Analytical Mechanics”: Joffe, “Problems in Mechanics”._ DEPARTMENT OF PHYSICS Professor F. N. Entwisle Assoc. Prof. E. Smith Mr. W. Hazell, Jr. Mr. P. Nielsen Mr. A. Zentgraf The Department of Physics is in charge of the course in Physics given to Freshmen and Sophomores, and of the course in Strength of Materials given to Juniors. It is the objective of the course in Physics to provide a knowledge of the fundamentals of the subject and to teach these fundamentals as prerequisite to later work in professional subjects rather than as basic principles in a discreet scientific subject. To this end the engineering aspects of the subject are stressed more than would be the case in General College Physics. The schedule of instruction includes a rather small amount of formal lecturing with a large amount of informal recitation and problem work together with one afternoon each week spent in Laboratory. Effort is made to unify the instruction in the class room and in the laboratory. The work in the latter, which is largely quantitative, is designed to present fresh problems for the students’ solution as far as possible rather than to require routine rechecking of known constants. The course in Strength of Materials is designed to present the fundamental causes of the strain in material under stress. Effort is made to present a course which may be of common benefit to each of the four professional departments in the College. Instruction is carried out by means of lectures and recitations and one-half day per week spent in the Laboratory. The laboratory is designed to demonstrate the theory presented in the class room and thus furnish visual evidence of the accuracy of theoretical assumptions. The Physics Laboratory
