The customised shaft has a diameter of 50 mm. A square parallel key is suggested to be used for mounting a gear into this shaft. The shaft is to be made of SAE 1095 Carbon Steel with a yield stress of 572 MPa. The gear is made from SAE 1045 Carbon Steel with a yield stress of 531 MPa. A key can be made of SAE 1018 Carbon Steel with a yield stress of 372 MPa or SAE 316 Stainless Steel of 241 MPa. The gear transmits torque of 2,000 +P N-m and has a hub length of 100 mm. The design factor is chosen as 3.0 and the width of the key is 12.7 mm. Specify the keys using two materials and explain which material should be recommended in such a design scenario.
