<p>
A slider crank mechanism is a common mechanical system that converts rotational motion into linear motion.
It consists of a crank, a connecting rod, and a slider.
The crank rotates about a fixed axis, the connecting rod connects the crank to the slider, and the slider moves linearly along a guide or track.
</p>
<p>
Here are some things to keep in mind when solving problems involving slider-crank mechanisms:
</p>
<ul>
<li>The velocity of the slider is purely tangential to the path of the slider.</li>
<li>The acceleration of the slider is purely tangential to the path of the slider.</li>
<li>The slider has a reaction force normal to the path of the slider.</li>
</ul>

The slider component of a slider crank mechanism has a reaction force like the "Roller/pin in confined slot" connection shown to the left.
