As part of an innovation policy introduced within the company to research into newer design of swings, the R and D department is proposing that work should be carried out on motorized swings. The initial consideration is to use an electric motor to spin the central shaft. For this purpose a hollow shaft of diameter ratio 3:5 is required to transmit 600 kW at 110 rpm, the maximum torque being 12% greater than the mean. The shear stress is not to exceed 60MPa and the twist in a length of 3m is not to exceed 1 Degree (1º). Calculate the minimum outer diameter (D) to satisfy both these conditions. Take G = 80GN/m2

Design a typical rigid flange coupling for connecting a motor and a centrifugal pump shafts. The coupling needs to transmit 15 KW at 1000 rpm. The allowable shear stresses of the shaft, key and bolt materials are 60 MPa, 50 MPa and 25 MPa respectively. The shear modulus of the shaft material may be taken as 84GPa. The angle of twist of the shaft should be limited to 1 degree in 20 times the shaft diameter. Note: show complete solution

In drilling a deep oil well the drill shaft, consisting of sections of “drill rod”, is powered from the top, while the load or counter torque is taken off at the bottom. The drill hole is 3 1/2 miles deep. Assuming a solid drill rod of circular cross section and 1 in. diameter, designed to a working shear stress of 5,000 psi, turning at 700 rpm, calculate (a) The wind-up, i.e. the twist angle between the top and bottom. (b) The horsepower of the driving motor. (c) State all assumptions, and comment on the results. What other considerations may have to be taken into account in using this drill? NOTE: The shear modulus of steel may be taken as 12 x 106 psi. Also 1 mile = 5,280 ft.
