A 300-lb cylinder is released from rest and rolls down without slipping. A linear unstretched spring (k=600 lb/ft) located down the inclined surface is used to stop the cylinder. The spring deformation in bringing the cylinder to rest is 14 inches. Determine (a) the coefficient of kinetic friction between the cylinder and the surface, (b) the linear velocity of the cylinder when it first contacts the spring.

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.
