Stress-Strain curve

Stress-Strain curve

Definition: The relationship between the stress and strain that a particular material display is known as that particular material's stress–strain curve.

Introduction of Beam & Types of Beam

Beam

A beam is a structural element that primarily resists loads applied laterally to the beam's axis. Its mode of deflection is primarily by bending. The loads applied to the beam result in reaction forces at the beam's support points. The total effect of all the forces acting on the beam is to produce shear forces and bending moments within the beam.

strength of material (introduction) part-1

introduction:

The strength of materials may be defined as that branch of engineering science which deals with the ability of various types of materials to resist its failure and their behavior under the action of the forces 

stress:

when some external system of forces or loads act on a body, the internal forces (equal and opposite) are set up at various sections of the body, which resist the external forces . this internal force per unit area at any section of the body is known as unit stress or simply stress. 

Mathematically,
