STEP 1: Convert Input(s) to Base Unit

Stress in Push Rod: 12.5 Newton per Square Millimeter --> 12500000 Pascal (Check conversion here)
Outer Diameter of Push Rod: 10 Millimeter --> 0.01 Meter (Check conversion here)
Inner Diameter of Push Rod: 8 Millimeter --> 0.008 Meter (Check conversion here)
Constant used in Buckling Load Formula: 0.000133 --> No Conversion Required
Length of Push Rod: 86.7 Millimeter --> 0.0867 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = (σ_c*pi/4*(d_o^2-d_i^2))/(1+a*((l^2)/((d_o^2+d_i^2)/16))) --> (12500000*pi/4*(0.01^2-0.008^2))/(1+0.000133*((0.0867^2)/((0.01^2+0.008^2)/16)))

Evaluating ... ...

P = 322.020506909502

STEP 3: Convert Result to Output's Unit

322.020506909502 Newton --> No Conversion Required

FINAL ANSWER

322.020506909502 ≈ 322.0205 Newton <-- Force on Push Rod

Symptoms of Pushrod failure

If the intake valve's pushrod is bent, the valve will come into contact with the piston. If a valve has been opened up because of a loose lock nut or if it has been adjusted with an incorrect clearance. It can make the valve bend.

How to Calculate Force Acting on Engine Push Rod given its Dimensions and Stress Generated?

Force Acting on Engine Push Rod given its Dimensions and Stress Generated calculator uses Force on Push Rod = (Stress in Push Rod*pi/4*(Outer Diameter of Push Rod^2-Inner Diameter of Push Rod^2))/(1+Constant used in Buckling Load Formula*((Length of Push Rod^2)/((Outer Diameter of Push Rod^2+Inner Diameter of Push Rod^2)/16))) to calculate the Force on Push Rod, Force acting on engine push rod given its dimensions and stress generated is the amount of force acting onto the end of a pushrod which is fitted with a lifter, upon which the camshaft makes contact. The camshaft lobe moves the lifter upwards, which moves the pushrod. Force on Push Rod is denoted by P symbol.
