Pulley Force Calculator:
Enter the values of total force applied, TF(N) and gravitational force, GF(N) to determine the value of pulley force, Fp(N).
Pulley Force Formula:
The pulley force formula is essential for determining the force exerted by or on a pulley system. Pulleys are used to lift heavy objects with less effort by changing the direction of the force applied.
Pulley force, Fp(N) in Newton is equated by the difference of total force applied, TF(N) in Newton and gravitational force, GF(N) in Newton.
Pulley force, Fp(N) = TF(N) – GF(N)
Fp(N) = pulley force in Newton, N.
TF(N) = total force applied in Newton, N.
GF(N) = gravitational force in Newton, N.
Pulley Force Calculation:
- Suppose you are using a pulley system to lift a 200kg object. The total force applied to lift the object is 2200N. Calculate the pulley force, considering the gravitational force (GF) as the weight of the object due to gravity (200kg * 9.8m/s²).
Given: TF(N) = 2200N, GF(N) = 200kg * 9.8m/s² = 1960N.
Pulley force, Fp(N) = TF(N) – GF(N)
Fp(N) = 2200 – 1960
Fp(N) = 240N.
- The total force (TF) applied and the pulley force (Fp) known, and you need to find the gravitational force (GF). If the total force applied (TF) is 2000N, and the pulley force (Fp) resulting from this action is 280N. Find GF.
Given: TF(N) = 2000N, Fp(N) = 280N.
Pulley force, Fp(N) = TF(N) – GF(N)
GF(N) = TF(N) – Fp(N)
GF(N) = 2000 – 280
GF(N) = 1720N.
