a. Compressive force acting on the contact area between two components having relative motion between them
b. Tensile stress acting on the contact area between two components having relative motion between them
c. Compressive force acting on the contact area between two components having no relative motion between them
d. Compressive stress acting on the contact area between two components having relative motion between them

ANSWER: Compressive stress acting on the contact area between two components having relative motion between them

The different types of stresses induced in mechanical components are:

1) Tensile stress
2) Compressive stress
3) Torsional shear stress
4) Bearing pressure
5) Direct shear stress
6) Bending stress

Bearing pressure:

- Localized compressive pressure acting between two components which have relative motion between them is called as bearing pressure.

- Bearing pressure = P / d l

here, d = diameter of pin, l = length of pin, P = force

- It is measured in N/mm2
