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.

Question

mecha

The figure shows a part of a machine used to crush recycled cans. Link ABC is attached
to the ground at pin A and link BD is attached to the piston D using also a pin connection.
When a=45°, 0=55°, and B-15°, the machine is about to start moving, i.e. impending
motion. If the coefficient of static friction and kinetic friction between the piston D and
the wall are us=0.25 and μ-0.2 respectively, find the magnitude of force applied to the
cans by the piston for P=200 kN.
