Theory of Machine A point B on a rigid link AB moves with respect to A with angular velocity ω rad/s. The radial component of the acceleration of B with respect to A, is (where vBA = Linear velocity of B with respect to A) vBA /AB vBA × AB v²BA /AB v²BA vBA /AB vBA × AB v²BA /AB v²BA ANSWER DOWNLOAD EXAMIANS APP
