The diagram below illustrates the inertia force and inertia torque acting on the connecting rod for crank angle θ = 50°. The inertia force and torque result in reaction forces at pin joints A and B. The object of the following numerical example is to find these reaction forces.
We look firstly at output characteristics of a crankshaft and flywheel under torque load conditions using crank effort diagrams. We then consider balancing of inertial forces and moments generated in the mechanism.
Sep 22, 2022 · A crank is simply an off-center connection that provides energy to (or takes energy from) a rotating wheel. As the crank pushes back and forth, the wheel rotates (or vice-versa).
A crank is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft. When combined with a connecting rod, it can be used to convert circular motion into reciprocating motion, or vice versa. The arm may be a bent portion of the shaft, or a separate arm or disk attached to it.
The diagram below shows the construction to find the velocity pole (instantaneous centre of rotation) of the connecting rod in our example mechanism where the crank angle = 50°. Construction of the velocity pole diagram is very straightforward.
A Crank and Slider mechanism / linkage, takes rotary motion and coverts it to linear motion. The diagram (below), shows how a piston pushes and pulls the connecting rod, which rotates the crank. This is typical of steam engines.

A crankshaft is a prominent part of the engine of a motorcycle. It is used to provide the driving power required to move various parts of the engine and to control and minimize the engine vibrations. The crankshaft used in motorcycles can be either cast crankshaft or forged crankshaft.
