Answer 2

Answer:

There are two kinds of forces acting on the crankshaft – 1. Gas pressure forces,     2. Inertial forces.

The gas pressure forces are caused due to the combustion in the engine during the power stroke. The gas pressure forces are directly related to the peak firing pressure.

Lets say Fp  is the maximum force caused due to combustion (Gas pressure forces).

Fp = (PFP) * (Cylinder bore area)

i.e. Fp = Pmax * Π / 4 * D2.
