A knuckle joint is to be design to connect two mild steel bars under a tensile load of 150 KN. The allowable stresses are 75Mpa in tension, 50Mpa in shear and 150 Mpa in crushing. (Assume empirical relations as Diameter of knuckle pin$ d_1 = d$ , Outer diameter of eye $d_2 = 2d$, diameter of knuckle pin head and collar $d_3 = 1.5d$, thickness of single eye t = 1.25d, thickness of fork $t_1 = 0.75d$, thickness of pin head $t_2 = 0.5d$)
- Draw neat sketch of knuckle joint.
- Find the diameter of the rod (d).
- Using empirical find all dimensions.
- With neat sketches for failure cross section areas check all components under different failures.
