Technician A says a converter that has a tight fit at the pilot hub could hold the converter drive hub and inner gear too far into the pump, causing cover scoring. Technician B says a front pump bushing that has too much clearance may allow the gears to run off center, causing them to wear into the crescent or the sides of the pump body.

Who is correct?

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
