## Prestress in the Tendon when Bearing Stress(fbr) is given Solution

STEP 0: Pre-Calculation Summary
Formula Used
prestress_force = bearing stress*Punching area
F = fbr*Apun
This formula uses 2 Variables
Variables Used
bearing stress - bearing stress is described as the contact pressure between the separate bodies. (Measured in Newton per Square Millimeter)
Punching area - Punching area can be described as the defined as the space occupied by a flat shape or the surface of an object. (Measured in Square Meter)
STEP 1: Convert Input(s) to Base Unit
bearing stress: 50 Newton per Square Millimeter --> 50000000 Pascal (Check conversion here)
Punching area: 50 Square Meter --> 50 Square Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
F = fbr*Apun --> 50000000*50
Evaluating ... ...
F = 2500000000
STEP 3: Convert Result to Output's Unit
2500000000 Newton -->2500000 Kilonewton (Check conversion here)
2500000 Kilonewton <-- Prestressing force
