Question

What is the formula for tensil strenght ?

Answer 1

1). s = F/A

Where;

s = the breaking strength (stress)
F = the force applied that caused the failure
A = the least cross- sectional area of the material
OR
(2). s = Mc/I

Where;

s = the breaking strength
M = the bending moment that caused the failure
c = distance from the neutral axis of the cross- sectional area to the extreme fiber subjected to tension
I = the moment of inertia of the cross-section of the material

Answer 2

Thanks :)
