Question

It is required to design a knuckle joint to connect two circular rods subjected to an axial tensile force of 40 kN. The rods are coand a small am of angular movement between their axes is permissible Design the joint and specify the dimensions of its components. Select suitable materials for the parts.

Note: Use Design data book for material selection. Select suitable factor of safety and Draw a sheet of Assembly and detail drawing of knuckle joint as per the dimensions after design.​

Answer 1

τ < 40N/m$m^{2}$

Explanation:

I select the material, II selects the safety feature, and so forth. Examine for strains in the eye VII Examine for stresses in the fork VIII Dimensional calculations V Dimensions d0 and d1 VI Check for eye stresses VII Check for fork stresses VIII The three-dimensional representation of the knuckle joint.

Knuckle joints are pin joints that enable rotation in one plane while transferring tension loads. Knuckle joints are commonly used to link rods that are subjected to tension in structures such as roof ties, bridges, and cranes. The links of a chain can also be thought of as a succession of knuckle joints.
