The crank and connecting rod of a petrol engine, running at 1800 r.p.m. are 50 mm and
200 mm respectively. The diameter of the piston is 80 mm and the mass of the reciprocating
parts is 1 kg. At a point during the power stroke, the pressure on the piston is 0.7 N/mm2
, when
it has moved 10 mm from the inner dead centre. Determine: 1. Net load on the gudgeon pin, 2.
Thrust in the connecting rod, 3. Reaction between the piston and cylinder, and 4. The engine
speed at which the above values become zero.
