Diameter of Fulcrum Pin of Rocker Arm given Bending Moment near Boss of Rocker Arm Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diameter of Fulcrum Pin = Length of Rocker Arm on Exhaust Valve Side-Bending Moment in Rocker Arm/Total Force on Rocker Arm of Exhaust Valve
d₁ = a-M_barm/P_e
This formula uses 4 Variables

Variables Used

Diameter of Fulcrum Pin - (Measured in Meter) - Diameter of Fulcrum Pin is the diameter of the pin used at the fulcrum joint.
Length of Rocker Arm on Exhaust Valve Side - (Measured in Meter) - Length of Rocker Arm on Exhaust Valve Side is the length of the arm (rigid member) of the rocker arm which is in connection with the exhaust valve.
Bending Moment in Rocker Arm - (Measured in Newton Meter) - Bending Moment in Rocker Arm is the amount of bending moment in the rocker arm (changes radial movement into linear movement) of any assembly.
Total Force on Rocker Arm of Exhaust Valve - (Measured in Newton) - Total Force on Rocker Arm of Exhaust Valve is the total force acting onto the rocker arm of the exhaust valve.

STEP 1: Convert Input(s) to Base Unit

Length of Rocker Arm on Exhaust Valve Side: 180 Millimeter --> 0.18 Meter (Check conversion here)
Bending Moment in Rocker Arm: 300000 Newton Millimeter --> 300 Newton Meter (Check conversion here)
Total Force on Rocker Arm of Exhaust Valve: 1926 Newton --> 1926 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d₁ = a-M_barm/P_e --> 0.18-300/1926

Evaluating ... ...

d₁ = 0.0242367601246106

STEP 3: Convert Result to Output's Unit

0.0242367601246106 Meter -->24.2367601246106 Millimeter (Check conversion here)

FINAL ANSWER

24.2367601246106 ≈ 24.23676 Millimeter <-- Diameter of Fulcrum Pin

(Calculation completed in 00.020 seconds)
