The horsepower which a shaft can transmit varies as the cube          of the diameter and the angular speed. If a 75-mm diameter          shaft transmits 270 hp when turning 1000 rpm, find the          horsepower which can be transmitted by a 125 mm shaft          rotating 1500 rpm.         A. 1250 hp                                        C. 1120 hp         B. 1565 hp                                        D. 1875 hp

Design of Shafts and Shaft Components

The shaft is basically defined as the machine element that rotates, is in circular cross-section, it is majorly used to transfer the power from one part of the system to another, or from a power generating machine to a power absorbing machine. The shaft is supported on bearings and is rotated with the help of a set of gears or pulleys that are used for the power transmission. Bending moment, torsion, and an axial force act upon the shaft. Designing of shaft primarily involves determining stresses at a critical point in the shaft that is arising due to loading.
