Design a cotter joint to connect two mild steel rods for a pull of 30 kN. The maximum permissible stresses are 55 MPa in tension; 40 MPa in shear and 70 MPa in crushing. Draw a neat sketch of the joint designed. - [Ans. d=22 mm; d, -32 mm; 7-14 mm; d, 44 mm; b=30 mm; a-12 mm; d = 65 mm; c=12 mm; d = 40 mm; 4-8 mm] Design a cotter joint to connect two mild steel rods for a pull of 30 kN.
