b) Calculate the minimum length of a parallel key for a gear which is to be mounted
on a 50 mm diameter shaft. The key is made from a material with an ultimate
tensile strength, Suts = 500 Mpa, and a yield strength of Sy = 400 Mpa. The gear
transmits a torque of 1850 Nm and has a hub length of 80mm. (Include a safety
factor of 2, and use ANSI recommendations for width of key). Comment on the
result.
