What is bending stress in beam?

When a beam is subjected to external loads, shear forces and bending moments develop in the beam. The beam itself must develop internal resistance to resist shear forces and bending moments. The stresses caused by the bending moments are called bending stresses.

How to Calculate Central Deflection of Leaf Spring?

Central Deflection of Leaf Spring calculator uses Deflection of Centre of Leaf Spring = (Span of Spring^2)/(8*Radius of Plate) to calculate the Deflection of Centre of Leaf Spring, The Central deflection of leaf spring formula is defined as the movement of the spring, either by applying force to it or removing force from it.
