Car steering systems convert rotary motion (steering wheel) into linear motion (turning wheels).

The crank is the rotating arm with the pedal attached, the rider's leg acts move it and this motion rotates the chainrings and then back wheel.

Car motors use a piston attached to a bar and a gear to create reciprocating compressor that make energy.

Treadle linkages use a rotary input to turn a crank on a fixed pivot. A connecting rod joins two moving pivots to another fixed pivot. This is how a pair of windscreen wipers works on a car, moving backwards and forwards together.

The engine's camshaft (the cam) operates the intake and exhaust valves (the followers) in accurate time with the pistons, controlling the flow of air and fuel for combustion.

Oil rigs move in an oscillating style, driven by a rotating body connected through a treadle linkage system, allowing them to perform their function.

A power saw is a quick return because of how it cuts faster on the return stroke then cutting stroke.

The train has toothed wheels that only go over the tracks with the same teeth. This converts the rotation of the wheels into moving the train forward through the tracks.

An electric gate uses a motor-driven gear (pinion) that meshes with a toothed linear bar (rack) attached to the gate

An arbor press converts the rotational motion of its handle into a downward linear force applied by the ram.

This is a quick return because the tool needs to return quickly after a cutting stroke.

A mechanical device that converts rotational motion into linear motion. It consists of a flat bar with teeth, which meshes with a small cylindrical gear called the pinion. When the pinion rotates, it forces the rack to move in a straight line, and when the rack moves, it can rotate the pinion

Rack railways:

Pinions on a locomotive engage a rack between the rails to provide traction on steep inclines.

Quick return mechanisms are commonly found in shaping machines, where they convert circular motion into reciprocating motion. The cutting action occurs during the forward stroke, while the return stroke is quicker, minimizing downtime and increasing productivity.

A drill press is an example of a rack and pinion system because it uses this mechanism to raise and lower the worktable or the drill head with precision.

The oscillating blades in some electric shavers use a crank-like mechanism to move back and forth.

A treadle linkage for windshield wipers is a type of mechanical system that uses a rotary input from a motor to produce a synchronized, oscillating (back-and-forth) motion in two or more wiper arms.

These machines, which are used to create internal keyways and splines, use a quick return mechanism to speed up the non-cutting part of the cycle.

Cams control the movement of the printing screen or other components during the printing and pulling process.

This is a cam and follower because it is using a rotating cam and a contacting follower. To convert rotational motion to reciprocating motion. The cam is a rotating disk.

# data[].attributes.body
The rotational motion of the gear(pinion) is turned into a liner motion because of the rack.

a picture of the crank and slider mechanism 

# data[].attributes.body
The part of a car that has a crank and slider mechanism is the piston and crankshaft assembly inside the engine. The piston acts as the slider, moving linearly within the engine cylinder. The crankshaft is the rotating component that has offset sections called "cranks". A connecting rod links the piston (slider) to the crankshaft (crank). As the piston moves up and down, the connecting rod pushes and pulls the crank, forcing it to rotate.

# data[].attributes.body
The crank shaft rotates the piston arm which brings them either up or down depending on where its at in the motion
