Formula Used

Radial Force at Crank Pin = Force on Connecting Rod*cos(Inclination of Connecting Rod With Line of Stroke+Crank Angle)
P_r = P_cr*cos(φ+θ)
This formula uses 1 Functions, 4 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

Radial Force at Crank Pin - (Measured in Newton) - Radial Force at Crank Pin is the component of thrust force on connecting rod acting at the crankpin in the direction radially to the connecting rod.
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.
Crank Angle - (Measured in Radian) - Crank Angle refers to the position of an engine's crankshaft in relation to the piston as it travels inside of the cylinder wall.

STEP 1: Convert Input(s) to Base Unit

Force on Connecting Rod: 19864.54 Newton --> 19864.54 Newton No Conversion Required
Inclination of Connecting Rod With Line of Stroke: 15.5939 Degree --> 0.272164898226693 Radian (Check conversion here)
Crank Angle: 30 Degree --> 0.5235987755982 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_r = P_cr*cos(φ+θ) --> 19864.54*cos(0.272164898226693+0.5235987755982)

Evaluating ... ...

P_r = 13900.0013593209

STEP 3: Convert Result to Output's Unit

13900.0013593209 Newton --> No Conversion Required

FINAL ANSWER

13900.0013593209 ≈ 13900 Newton <-- Radial Force at Crank Pin

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.
