Two beams are joined end to end and hinged at the left end. The left beam has a mass of 10 kg and the right beam has a mass of 12.2 kg. Determine the magnitude of the gravitational torque about the hinge. Use g = 10 N/kg. Enter units as Nm. Hint: You can either determine the center of mass of the combined object and exert the total gravitational torque from there or you can treat each beam individually and add the torques of each.
Three bodies are fixed on a shaft rotating at 500 rpm. The mass of the bodies are 3.5 kg, 2.5 kg and 2 kg. The radii of rotation can be taken as 60 cm, 40 cm and 25 cm. If a balancing body of 1.5 kg is to be placed, then find the unbalance in the system. The first body can be assumed to be at 45° from positive x axis, second body is at 90° from first body and third body is at 180° from positive x-axis. All the angles are measured in anti-clockwise direction.
