l. A 400N weight is supported by a uniform beam with a mass of 30-kg and a length of 1.6 metets. The beam is connected to a wall through a hinged connection at point C and a cable as shown below. If the system is in static equilibrium, draw a free~body diagram and determine; a. The cable's tension. b. The reaction forces at the hinge (Rx and Ry). 2. A rowing machine consists of a solid disk with a radius of Zicm and a mass of 19-kg. An athlete pulls on the attach-ed cable with a force of IOsNewtons and causes the disk to accelerate. If the disk starts from rest, determine; The disk's moment of ihertia. The magnitude of the torque applied by the athlete. The disk's angular acceleration. The disk's angular momentum at t = 5.0 sec. 999'.\
