Force acting on piston top due to gas pressure given thrust force on connecting rod Solution

STEP 0: Pre-Calculation Summary

Formula Used

Force on piston head = Force on connecting rod*cos(Inclination of connecting rod with line of stroke)
P = P_cr*cos(φ)
This formula uses 1 Functions, 3 Variables

Functions Used

cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)

Variables Used

Force on piston head - (Measured in Newton) - Force on piston head is the force due to the combustion of gases onto the top of a piston head.
Force on connecting rod - (Measured in Newton) - Force on connecting rod is the force acting on the connecting rod of an IC Engine during operation.
Inclination of connecting rod with line of stroke - (Measured in Radian) - Inclination of connecting rod with line of stroke is the angle of inclination of the connecting rod with the line of stroke of the piston.

STEP 1: Convert Input(s) to Base Unit

Force on connecting rod: 19700 Newton --> 19700 Newton No Conversion Required
Inclination of connecting rod with line of stroke: 15.5 Degree --> 0.27052603405907 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Failure of Connecting Rod

Failure of a connecting rod often called "throwing a rod", is one of the most common causes of catastrophic engine failure in cars, frequently driving the broken rod through the side of the crankcase and thereby rendering the engine irreparable. Common causes of connecting rod failure are tensile failure from high engine speeds, the impact force when the piston hits a valve (due to a valvetrain problem), rod bearing failure (usually due to a lubrication problem), or incorrect installation of the connecting rod.
