Two cylinders A and B, having a weight of 10lb and 5lb, respectively, are attached to the ends of a cord which passes over a 3-lb pulley. If the cylinders are released from rest, determine their speed in t= 0.5 sec. The cord dose not slip on the pully. Neglect the mass of the cord.

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

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
