Direct Stresses :

The Stresses which are acting normal to the plane of the body are called as normal or direct stresses.

These are called normal because these are acting perpendicular to the plane of the body.

Shearing Stresses :

The Stresses which act parallel to the stressed surfaces are called as shearing stresses.

Tensile Stresses :

If a straight bar is subjected to a pair of collinear forces acting in opposite direction and coinciding with the ends of the bar and directed away from the bar, then the bar tends to increase in length and theĀ  stresses developed in the bar will be tensile.

Compressive Stresses :

If a straight bar is subjected to a pair of collinear forces acting in opposite direction and coinciding with the ends of the bar and directed towards the bar, then the bar tends to shorter in length and the stresses developed will be compressive stresses.
