Force on crank pin given crank pin length, diameter and bearing pressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

Force on Crank Pin = Bearing Pressure in Crank Pin*Diameter of Crank Pin*Length of Crank Pin
f_pin = Pb_pin*d_pin*l_c
This formula uses 4 Variables

Variables Used

Force on Crank Pin - (Measured in Newton) - Force on Crank Pin is the force acting onto the crankpin used in the assembly of the crank, and the connecting rod.
Bearing Pressure in Crank Pin - (Measured in Pascal) - Bearing Pressure in Crank Pin is the compressive force acting on the contact area between two components of crank pin and bushing having no relative motion between them.
Diameter of Crank Pin - (Measured in Meter) - Diameter of Crank Pin is the diameter of the crank pin used in connecting the connecting rod with the crank.
Length of Crank Pin - (Measured in Meter) - Length of Crank Pin is the size of the crankpin from one end to the other and tells how long is the crankpin.

STEP 1: Convert Input(s) to Base Unit

Bearing Pressure in Crank Pin: 9.447674 Newton per Square Millimeter --> 9447674 Pascal (Check conversion here)
Diameter of Crank Pin: 48 Millimeter --> 0.048 Meter (Check conversion here)
Length of Crank Pin: 43 Millimeter --> 0.043 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f_pin = Pb_pin*d_pin*l_c --> 9447674*0.048*0.043

Evaluating ... ...

f_pin = 19499.999136

STEP 3: Convert Result to Output's Unit

19499.999136 Newton --> No Conversion Required

FINAL ANSWER

19499.999136 ≈ 19500 Newton <-- Force on Crank Pin

What is connecting rod?

The connecting rod is a connection between the piston and a crankshaft. It joins the piston pin with the crankpin. The small end of the connecting rod is connected to the piston pin and the big end to the crank pin. The purpose of the connecting rod is to convert the linear motion of the piston into the rotary motion of the crankshaft.

Shape of Connecting Rod

The connecting rod consists of an I-beam cross-section and is made of forged steel. Aluminum alloy is also used for connecting rods. They are precisely matched in sets of similar weight in order to maintain engine balance. The lighter the connecting rod and piston, the greater the resulting in power and the lesser the vibration because the reciprocating weight is less. The connecting rod carries the power thrust from the piston to the crankpin and hence it must be very strong, rigid, and also as light as possible.
