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
The drag force on an object depends on the dimensionless drag coefficient, the density of air, the object velocity, and the frontal area of the object. By only considering units obtain a relation for the drag force.
The lever BCD is hinged at C and attached to a control rod at B. If P = 100 lb, determine the tension in rod AB and the reaction at C, using both the graphical method and the analytical method base on force decomposition.
