10. Two identical 10-kg spheres are attached to the light rigid rod, which rotates in the horizontal plane centered at O. If the spheres are subjected to tangential forces of P = 10 N, and the rod is subjected to a couple moment M = (8t) N- m, where t is in seconds, determine the speed of the spheres at the instant t = 4 s. The system starts from rest. Neglect the size of the spheres. P- 10 N 0.5m 0.5 m M- (80) N-m P= 10 N

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
