A 15/16 in. wide key has depth of 5/8 in. It is 12 inches long and is to be used on a 200 hp, 1160 rpm, squirrel-cage induction motor. The shaft diameter of 3 7/8 inches. The maximum running torque is 200% of the full-load torque. Compute the maximum torque (ans: 21,733 in-lb) Please show solution.

Expert Solution

To solve the given problem, we shall first find the value of full load torque using the equation/correlation betweebn Power and Torque. Then, we shall multiply fullload torque with 2 to get maximum Torque. This is because the value of maximum torque is 200 percent of full load torque.There is no use of key dimensions in this question.

Please refer to the attached images for solution of given problem and do comment in case of any query. All the best!!

A microwave has a width of 29 inches, depth of 15 inches, and a height of 16 inches. The power of the microwave is 1.65 kW. Use this information to solve these questions. Assume that microwave energy is generated uniformly on the upper surface of the cavity and propagates directly downward toward the base. The base is lined with a material that completely absorbs microwave energy. (c = 3.00 × 108 m/s, μ0 = 4π × 10-7 T ∙ m/A,...
