A 0.2-kg pendulum bob A hangs from a 0.75 m cord attached to a fixed pivot. It is released from rest at point 1 when the cord is horizontal and without slack, and swings down to strike 0.2-kg bob B at point 2. The coefficient of restitution between the two bobs is e = 0.7. Neglect the size of the bobs and the mass of the cords. 0.75 m 1 For parts b-f below, consider bob A at the instant the cord is vertical, when it has reached point 2, and immediately before the collision: а) What is the tension in the cord of the stationary bob B? b) Draw a clear and complete free body diagram of bob A. c)( Find the speed of bob A. d) Find the tangential acceleration of bob A. e) Find the normal acceleration of bob A. f) Find the tension in the cord of bob A. g) Find the speed of bob A immediately after the collision.

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.
