Abearing uses sae 30 oil with a viscosity of 0.1 n·s/m2. the bearing is 30 mm in diameter, and the gap between the shaft and the casing is 2.0 mm. the bearing has a length of 3 cm. the shaft turns at ω = 350 rad/s. assuming that the flow between the shaft and the casing is a couette flow, find the torque required to turn the bearing.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
