1. A six-cylinder two-stroke engine with a compression ratio = 9 produces a torque of 1100 Nm at a speed of 2100 rpm. It has a bore bof 123 mm and a stroke s of 127 mm. (a) What is the displacement volume and the clearance volume of a cylinder? (b) What is the engine bmep, brake power, and mean piston speed?

A single pass rice mill was tested for 30min. and gave the following results: input paddy 10000 kg, milled rice produced-6,500 kg, broke produce 1500 kg and weight of headrice-2000 kg. Compute the following: (a) Throughput capacity, (b) % Milling recovery, (c) Broken grain, and (d) % Head rice recovery.

The output shaft diameter is typically larger than the input shaft diameter on worm drive gearboxes.  Explain why
