The  steering system  converts the rotation of the  steering  wheel into a swiveling movement of the road wheels in such a way that the  steering -wheel rim turns a long way to move the road wheels a short way. The  system  allows a driver to use only light forces to  steer  a heavy car

A  mountain bike  ( MTB ) or mountain bicycle is a bicycle designed for off-road cycling.

One piston, the uppermost one in the  animation , has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. ... The  radial engine  normally uses fewer cam lobes than other types

The most common use of  V12 engines  in the 21st century has been marine  engines , railway locomotives, large stationary  engines  and European sports/luxury cars

Universal  joints allow drive shafts to move up and down with the suspension while the shaft is moving so power can be transmitted when the drive shaft isn't in a straight line between the transmission and drive wheels. Rear-wheel-drive  vehicles  have  universal  joints (or U-joints) at both ends of the drive shaft.

The functions of the  pistons  are  to transmit the gas forces via the connecting rod to the crank shaft,  to seal - in conjunction with the  piston  rings - the combustion chamber against gas leakage to the crankcase and to prevent the infiltration of oil from the crankcase into the combustion chamber,  to dissipate

A  crankshaft  is used wherever there is a need to convert energy and power into rotary movements. ...  Crankshafts  are used in a wide variety of engines, from motorised chain saws and cars to diesel engines in ships

Oscillating cylinder  steam  engines  are now mainly used in toys and models but, in the past, have been used in full-size working  engines , mainly on ships and small stationary  engines . ... They also tend to be more compact than other types of a  cylinder  of the same capacity, which makes them advantageous for use in ships
