    1) Crushing stress:

    - Compressive stress acting on the contact area between two components having no relative motion between them is known as crushing stress.
    - Cotter joint is used to connect co-axial rods rigidly. They have no relative motion between cotter and socket collar.

    2) Tensile stress: It is the stress which tends the material to expand and increases length of the material in tensile direction.
    - Stress is measured in N / m2 or pascal.

    3) Direct shear stress: The component of stress coplanar with cross-section of a material is called as direct shear stress.
    - It is calculated using the formula: τ = F / A
