The thin rectangular block is supported at its corners by small rollers resting on smooth horizontal surfaces. If b=0.5 m and h = 0.3 m, calculate the magnitude of the angular acceleration of the block at the moment when the supporting surface at B is suddenly removed. Present your answer in rad/sec² using 3 significant figures. b h B

Need only a handwritten solution only (not a typed one).

Problem 2: Rod AB has a mass of 10-kg and a uniform cross-sectional area. The piston has a mass of 15-kg. If the flywheel rotates at a constant angular velocity of 500 rev/min, determine the forces on A and B when 8 = 60°. Use a Vector Approach, show all your work. 150 mm, 750mm

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A uniform slender rod of length L = 900 mm and mass m = 4 kg is suspended from a hinge at C. A horizontal force P of magnitude 75 N is applied at end B. A Ja B C P Determine the corresponding angular acceleration of the rod. The corresponding angular acceleration of the rod is rad/s² O.
