Question

The connecting rod AB of a certain internal-combustion engine weighs 1.24 lb with mass center at G and has a radius of gyration about G of 1.20 in. The piston and piston pin A together weigh 1.96 lb. The engine (link OB) is running at a constant speed of 2040 rev/min. Neglect the weights of the components and the force exerted by the gas in the cylinder compared with the dynamic forces generated and calculate the magnitude of the force on the piston pin A for the crank angle 0 = 90°. (Suggestion: Use the alternative moment relation, MB = IBQ + 7 x mag as the moment center.) 3.1" 1.4" 1.6"
