Answer to Question #270437 in Mechanical Engineering for hamad

Question

The motion of a cylinder of radius r is controlled by a cable AG. Knowing that end G of the cable has a

velocity of VG = 0.3 m/s and an acceleration of aG, = 0.5 m/s' , both directed upward, and that r = 0.15 m

determine the acceleration (a) of point B and of point D, (b) the velocity and acceleration of point E.

Answer 1

acceleration, the rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing. For all other kinds of motion, both effects contribute to the acceleration.
