We all come in touch with the word stress in our day-to-day life when some external thing has an impact on our state of mind. Likewise in Physics, stress is the external restoring force acting on per unit area.
Stress is denoted by σ. It is represented as N/m2.
Stress formula is articulated as
F =Force applied
A =Area on which force is acting
Stress formula is made use of to find stress applied on any given body if force and area on which force is exerted is given in the problem.
Stress Solved Examples
Underneath are problems based on stress which may be useful for you.
Problem 1: Find the stress if a force of 50 N is acting on an area of 5 mm2?
Given: Force F = 50 N,
Area A = 5mm2
F (Force) = 1000 N,
A (Area) = 0.2 m2
