1. Determine the horizontal and vertical com shown in Figure 1. At the given position o- 6 rad/sec and a -15 rad/sec2, both clockwise. Also, determine the velocity of point A ?? 1.5 m Figure 1.

Solution

Find out tangential (a_t) and radial (centripetal) acceleration (a_r)

a_t = ?r = 15 x 1.5 = 22.5 m/s2,

a_r = ?²r = 6² x 1.5 = 54 m/s2

velocity v = ?r = 6 x 1.5 = 9 m/s
