Question 6 (20 pts): Cylinders A and B are supported in a cradle as shown. Neglect friction. $r_A = r_B = 0.4 \text{ m}$, $m_A = m_B = 100 \text{ kg} = 980N$ a) Draw FBDs of each cylinder separately. Include any angles needed to solve (neglect friction). b) Find all the forces acting on cylinder A. Be sure to unambiguously indicate the directions of each force. c) If cylinder A remains unchanged and cylinder B has twice the radius and twice the mass, draw a new FBD of cylinder B and find the angles of all forces on the FBD.

An oil of viscosity 5 poise is used for lubrication between a shaft and sleeve. The diameter of the shaft is 500 mm and it rotates at 200 rpm. The thickness of the oil film is 0.2 cm. Calculate the power lost in the oil for a sleeve length of 100 mm. If the speed is reduced to 100 rpm keeping the other parameters constant, what will be the power lost? Compare the result and comment on the effect of speed on the power lost.
