[[File:Involute wheel.gif|frame|Two [[involute gear]]s, the left driving the right: Blue arrows show the contact forces between them. The force line (or [[Gear#Nomenclature|line of action]]) runs along a tangent common to both base circles. (In this situation, there is no force, and no contact needed, along the opposite common tangent not shown.)  The involutes here are traced out in converse fashion: points (of contact) move along the ''stationary'' force-vector "string" as if it was being unwound from the left ''rotating'' base circle, and wound onto the right ''rotating'' base circle.]]

In manufacturing, mechanization replaced hand methods of making goods. Prime movers are devices that convert thermal, potential or kinetic energy into mechanical work.  Prime movers include internal combustion engines, combustion turbines (jet engines), water wheels and turbines, windmills and wind turbines and steam engines and turbines. Powered transportation equipment such as locomotives, automobiles and trucks and airplanes, is a classification of machinery which includes sub classes by engine type, such as internal combustion, combustion turbine and steam. Inside factories, warehouses, lumber yards and other manufacturing and distribution operations, [[material handling]] equipment replaced manual carrying or hand trucks and carts.<ref name="Jerome 1934"/>

In mining and excavation, power shovels replaced picks and shovels.<ref name="Jerome 1934"/>  Rock and ore crushing had been done for centuries by water-powered [[trip hammer]]s, but trip hammers have been replaced by modern ore [[crusher]]s and [[ball mill]]s.

[[Bulk material handling]] systems and equipment are used for a variety of materials including coal, ores, grains, sand, gravel and wood products.<ref name="Jerome 1934"/>

Construction equipment includes [[crane (machine)|cranes]], [[concrete mixer]]s, [[concrete pump]]s, [[cherry picker]]s and an assortment of power tools.
