The two balls are attached to the light rigid rod, which is suspended by a cord from the support above it. If the balls and rod, initially at rest, are struck with the force F = 17.0 lb, calculate the magnitudes of the corresponding acceleration a of the mass center and the rate 0 at which the angular velocity of the bar is changing. 7.1" 4.0" 6.1" 11.7" Answers: a= 79.104 i 4.06 lb 2.86 lb ft/sec ! rad/sec The two balls are attached to the light rigid rod, which is suspended by a cord from the support above it.
