Mechanical control systems

Mechanical control systemsuse parts for movement/force control. They include input, process, and output. Types of motion: linear, rotary, reciprocating, oscillating.

Construction kits are quick but limited, working models are precise but time-consuming, virtual models save materials but need training.

Levers use mechanical advantage to ease lifting; a bar and a pivot (fulcrum) with effort, fulcrum, and load arranged differently in first, second, and third class levers

Power transmission transfers mechanical power. Gear trains change speed/torque. Idler gears reverse rotation. Belts/pulleys and chains/sprockets transfer motion efficiently.

A cam is a rotating part on a crankshaft that moves a follower: types include eccentric, pear, heart, and snail cams, with flat and roller followers handling loads differently.
