A rigid link 2 illustrated in the figure on the right is rot

A rigid link 2 illustrated in the figure on the right is rotating clockwise with known accelerations = 80 in/sec^2 at 0 degree and A_B = 190 in/sec^2 at 270 degree at points A and B respectively. The lengths of sides AB and AC are: R_AB = 1.8 in. and R_BC = 1.4 in. Using the graphical acceleration polygon method, find: alpha_2 and omega_2, the angular acceleration and angular velocity, A_c, the acceleration of point C.

Solution

The answer of following question is as follows.

The value of angular velocity is 54 rad/sec while angular acceleration is 67 rad/sec2
