Extracted text: 2. Bar AB starts from rest at 0 = 0 with the constant angular acceleration of 6 rad/sec?. The block of mass m begins sliding on the bar When e = 45 degrees, 0.20 m a. Compute time for the bar to reach 45 degrees from the horizontal b. Compute the normal reaction between the bar and block. c. Determine the coefficient of static friction between the block and the bar.
