Cotter and Knuckle Joints

Cotter joint is used when the members are subjected to which type of stresses?

• Axial tensile

• Bending load

• Axial tensile or compressive

• Torsional load

In a gib and cotter joint, the gib and cotter are subjected to

• single shear only

• double shear and crushing

• single shear and crushing

• double shear only

A cotter joint is to support a load varying from 30 kN in compression to 30 kN in tension. The load is applied statically with Tensile stress = compressive stress = 50 MPa ; shear stress = 35 MPa and crushing stress = 90 MPa.Find Diameter of the rods.

Which of the following are important parts of knuckle joint?

• Eye

• Pin

• Fork

• Each of the mentioned

Calculate the diameter of pin in a knuckle joint from shear consideration with maximum shear stress allowed is 40N/mm² and an axial tensile force of 50kN is acting on the rod.

• 39mm

• 44mm

• 49mm

• 101 mm
