Variables Used
Force on Push Rod - (Measured in Newton) - Force on Push Rod is defined as the force (a push or pull on the pushrod resulting from its interaction with another part) that is acting onto the pushrod.
Stress in Push Rod - (Measured in Pascal) - Stress in Push Rod is defined as the force per unit area within the push rod material that arises due to the externally applied forces onto it.
Outer Diameter of Push Rod - (Measured in Meter) - Outer Diameter of Push Rod is the external diameter or the outside surface diameter of the push rod.
Inner Diameter of Push Rod - (Measured in Meter) - Inner Diameter of Push Rod is the internal diameter or the inside surface diameter of the push rod.
Constant used in Buckling Load Formula - Constant used in buckling load formula is a constant used in the calculation of critical buckling load in a member.
Length of Push Rod - (Measured in Meter) - Length of Push Rod is the size of the push rod from one end to another end (how long the rod is).
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 = (σc*pi/4*(do^2-di^2))/(1+a*((l^2)/((do^2+di^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.
