The lengths of crank and connecting rod of a horizontal engine are 300 mm and 1.2 m respectively. When the crank has moved 300 from the inner dead centre, the acceleration of the piston is 35m/s2.
The average frictional resistance to the motion of the piston is equivalent to a force of 550N and net effective steam pressure on piston is 500kN/m2 .
The diameter of the piston is 0.3 m and mass of reciprocating parts is 160 kg. Determine (i) Reaction on the cross head guides (ii) Thrust on the crank shaft bearings and (iii) Torque on the crank shaft
