Tech A says that measuring piston ring end gap in the cylinder bore will verify that the rings are properly sized for the bore. Tech B says that measuring piston-to-cylinder bore clearance determines the compression ratio of the cylinder. Who is correct

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
