Acircular cylindrical shaft 50 mm in diameter and 100 mm long rotates at 15,000 rev/min inside a sleeve 50.1 mm in diameter. the clearance is filled with oil, of kinematic viscosity v = 0.003 m/s and specific gravity, sg = 0.88. determine the torque and the corresponding power required to rotate the shaft

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
