Asteel shaft 5 m long, having a diameter of 50 mm, is to transmit power at a rotational speed of 600 rev/min. if the maximum shear stress is limited to 60mn/m^2. determine the following. (i) the maximum power that can be transmitted. (ii) the corresponding angle of twist. assume the modulus of rigidity for steel is 80 gn/m^2

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
