Description
Levers of any of the 3 Classes may be combined such that the load of one lever is the effort applied to another.
This can be done to increase Mechanical Advantage (especially where operating space is restricted) or to increase movement as with a piano key mechanism for example.
Features and Uses
Common examples of Compound Lever applications include: nail clippers, bolt cutters, bench shears, 'aviation' type tinsnips, bass drum pedal and mechanical typewriter mechanisms.
Animations
