You are asked to design a plain surface journal bearing to carry a steady radial load of 5.75 kN while the shaft rotates at 950 rpm. The shaft stress analysis determines that an acceptable nominal diameter of the journal is 62.5-mm and an l/d ratio is 1. The shaft is part of a machine requiring good precision. So a minimum radial clearance cmin= 0.040 mm seems appropriate. We shall use SAE 30 oil as a lubricant, at an inlet temperature of 45 oC. Analyze the hypothetical bearing,a) Determine the operating temperature Tave, and operating viscosity μave. b) Determine the minimum film thickness, ho, temperature rise of the lubricant, ΔTC, the total oil flow, Q, and side flow Qs in [mm3/s], the maximum film pressure Pmaxdeveloped in [MPa]. c) Determine the power loss, Hloss in [W], friction torque, Tf in [N-m] d) For minimum radial clearances, perform a design assessment using Trumpler’s criteria.
FLUID MECHANICS An 8-in diameter piston is pushed inside a cylinder having an 8.005 in diameter. The gap is filled with a lubricant (v=0.003 ft^2/s, SG= 0.80). If the piston is moving at 0.5 ft/s, find the frictional resistance when there is an engagement of 10 ft.

A steel shaft 100mm in diameter is loaded and support in shaft bearing 0.4m apart. The shaft carries three loads: first mass 12kg at the centre, second mass 10kg at a distance 0.12m from the left bearing and third mass of 7kg at a distance 0.09m from the right bearing. Find the value of the critical speed by using Dunker ley’s method if E = 2X1011N/m2.
