Meriam, Kraige & Bolton — Kinematics of Particles: Problem 2_140

2/140 The vertical shaft of the industrial robot rotates at the constant rate \(\omega\). The length \(h\) of the vertical shaft has a known time history, and this is true of its time derivatives \(\dot{h}\) and \(\ddot{h}\) as well. Likewise, the values of \(l, \dot{l},\) and \(\ddot{l}\) are known. Determine the magnitudes of the velocity and acceleration of point \(P\). The lengths \(h_0\) and \(l_0\) are fixed.
