Value
R₂
F; is the force applied to the pedal
R: is the pedal radius
F, is the force acting on the main crank, due
to chain contact
Remember:
T = FR
Compound Gear Ratio - R₁/R; x Ra/Ra
R; is the main crank radius
F, is the force acting on the rear gear, due
to chain contact
R; is the rear gear radius
F. is the force acting on the rear wheel, due
to contact with the ground. Note that the
coefficient of static friction between wheel
and ground must be large enough to
support this force, otherwise slipping
occurs
R4 is the rear wheel radius
