It relates stress (force per unit area) to strain (proportional deformation) along an axis or line.The basic principle is that a material undergoes elastic deformation when it is compressed or extended, returning to its original shape when the load is removed. Result. ENGINEER p – Distance between the point of suspension of the mass and nearer knife edge. For example, the effective bending modulus of a beam is constant for all cross-sectional areas and is equal to the tensile modulus.
