A crankshaft must be able to accommodate the force generated by the engine without being permanently deformed. It must also be flexible.

Engines that make their power with pistons usually need a way of converting back-and-forth (reciprocating) motion into round-and-round (rotational) motion—a way of driving a wheel, in other words. Most engines use cranks to do this. A crank is simply an off-center connection that provides energy to (or takes energy from) a rotating wheel. As the cr...
Cams generally do the opposite job to cranks: they turn rotary motion into reciprocating motion. Whatever you need to move up and down (or back and forth) rests on top of an oval wheel, sometimes mounted off-center (the cam). As the cam rotates, the object it supports rises up and down. In this example, you can see the blue box rises and falls as t...
It's all very well to talk about things in theory with little animated graphics, but it's muchmore interesting to see how these things work in actual machines. The following selection of photosshows you some examples of cranks working hard in real life.
From door locks and prosthetic legs to old-fashioned (gear-driven)calculators and photocopiers, cams are working theirmagic inside all kinds of machines, turning rotation into back and forth motion. It's almost impossible to find good pictures of working cams, but I'm constantly looking out for examples; I'll post more here as I discover them.
Cranks are closely related to levers and gears: all three of these can be used to magnify force or speed, although not both at the same time. Suppose you're turning the handle of the clockwork radio in our top picture. Your hand goes round in a larger circle than the mechanism in the center, so it's traveling faster. A crank used in this way reduce...
Crankshaft: Working, Construction, Functions, Diagram. The crankshaft is the first rotating component in a reciprocating engine that is driven by a single or multiple reciprocating pistons. It is also found in several applications that involve the conversion between rotating and reciprocating motion.
In this tutorial we expand free body diagrams to include inertia forces and inertia torques generated in the individual elements (slider, connecting rod and crank arm), a general topic known as kinetics.

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.
