Load is the external force acting on a body. In SI system load is measured in newton.
Tensile load :- Increase in the length of the member in the direction of applied load.
Compressive load :- Decrease in the length of the member in the direction of the applied load.
Bending load :- The load whose cause Bending or curvature problem in the member are called shearing load.
Shear load :- The load cause sliding of one face of the member relative to the other face of the member.
