“Give me a foothold and I will move the world.” Archimedes
Lever resolution is based on the “moment of a force about a point” and the principle of equilibrium.
M F = F d
MF = 0
A) Yes,
Bp P = Br R
Where,
Power (P): force exerted on the lever in order to move a weight.
Resistance ( R ): Force to move using the lever.
Support point (O): place where the lever pivots.
Power arm (Bp): distance between the support point (O) and the point where the power is applied (P).
Resistance arm (Br): distance between the support point (O) and the point where the resistance is applied ( R ).
