Lifting Wheels
Lifting wheels and effort force
Sponsored Links
The effort force with a lifting wheel can be calculated as
F = W d / D (1)
where
F = effort force (N)
W = m a = weight of body (N)
d = wheel inner diameter (m)
D = wheel outer diameter (m)
m = mass of lifted body (kg)
a = 9.81 m/s2 - acceleration of gravity
Example - Effort Force with a lifting wheel
A body of mass 100 kg is lifted with a lifting wheel with inner diameter 0.1 m and a outer diameter 0.3 m. The effort force can be calculated as
F = (100 kg) (9.81 m/s2) (0.1 m) / (0.3 m)
= 327 N
