The 4.8 m I-beam has a mass of 900 kg and is held in the horizontal position by the pin at O and by the vertical cable which passes around the pulley at A and around the drum of the 200 kg motorized winch at B, as shown in Figure 8. If the winch motor has an output starting torque of 800 N.m, calculate the reaction forces at the pin O given the moment of inertia of the whole system including the winch, lo 7272 kg.m?. Treat the beam as a slender bar and the winch unit as a mass concentrated at the centre of the pulley.

SECW OM A motorbike wheel with an 8 kg mass has a 0.4 m radius of gyration around the z-axis, as shown in Figure. The wheel's shaft is supported by bearings A and B and rotates at a constant rate of 150 rpm in a counter-clockwise direction from the z-axis, while the frame rotates at 12 rpm in a counter- clockwise direction from the y-axis. Determine the resultant reaction forces at each bearing A and B due to the mass and gyroscopic effects. With the result of forces, which bearing has a tendency to fail first, which bearing should be considered for design purposes and explain the effect on motor if the bearing fail. y 0.55 0.4 All dimensions in meter (m)
