Rod OA rotates about O in a horizontal plane. The motion of the 300-g collar B is defined by the relations r and e = 7( – 30), where r is expressed in millimeters, t in seconds, and 0 in radians. Determine the radial and transverse components of the force exerted on the collar when (a) t = 0, (b) t = 0.5 s. 300 + 100 cos (0.5 1t) %3D %3D
