Question
A (25 kW, 500 rpm) motor has a mild steel
shaft of (30 mm) diameter and (8 cm) length.
There are two parallel keys available A (w = 12
mm, t = 10 mm) and B (w = 10 mm, t = 8 mm),
suggest one of them to connect the shaft with
a pulley. use torsional shear stress = 160 MPa,
tensile strength = 400 MPa, compression
strength=280 MPa, bending strength= 380,
factor of safety=3.
