Enter the values of load, L_{(N)}, pitch of the screw, p_{(m)} and radius of the effort arm, r_{(m)} to determine the value of Screw Jack Force, F_{sj(N)}.

__Screw Jack Force Formula:__

__Screw Jack Force Formula:__

The screw jack force formula is utilized to determine the force required to lift or lower a load using a screw jack, a device that converts rotational motion into linear motion.

Screw Jack Force, F_{sj(N)} in Newtons, is calculated by dividing the product of the load, L_{(N)} in Newtons and the pitch of the screw, p_{(m)} in metres by the product of 2pi and the radius of the effort arm, r_{(m)} in metres.

Screw Jack Force, F_{sj(N)} = L_{(N)} * p_{(m)} / 6.28 * r_{(m)}

F_{sj(N)} = screw jack force in Newton, N.

L_{(N)} = load in Newton, N.

p_{(m)} = pitch of the screw in metres, m.

r_{(m)} = radius of the effort arm in metres, m.

- Determine the force required to lift a 1500N load with a screw jack that has a screw pitch of 0.01m and an effort arm radius of 0.05m.

Given: L_{(N)} = 1500N, p_{(m)} = 0.01m, r_{(m)} = 0.05m

Screw Jack Force, F_{sj(N)} = L_{(N)} * p_{(m)} / 6.28 * r_{(m)}

F_{sj(N)} = 1500 * 0.01 / 6.28 * 0.05

F_{sj(N)} = 47.77N.

- Suppose you need to calculate the effort arm radius required to lift a load of 1000N using a screw jack. The pitch of the screw is 0.005m, and the force applied is 50N.

Given: L_{(N)} = 1000N, p_{(m)} = 0.005m, F_{sj(N)} = 50N

Screw Jack Force, F_{sj(N)} = L_{(N)} * p_{(m)} / 6.28 * r_{(m)}

r_{(m)} = L_{(N)} * p_{(m)} / 6.28 * F_{sj(N)}

r_{(m)} = 1000 * 0.005 / 6.28 * 50

r_{(m)} = 0.0159m.
