__Lever Torque Formula:__

The lever torque formula is used to calculate the torque or turning force exerted by a lever, a fundamental principle in physics and mechanics that allows small forces to move larger weights by utilizing the lever’s length.

Lever Torque, T_{L(N.m)} in Newton metres, is determined by multiplying the force, F_{(N)} applied in Newtons, by the distance, D_{(m)} in metre from the pivot point (the fulcrum) to the point where the force is applied.

Lever Torque, T_{L(N.m)} = F_{(N)} * D_{(m)}

T_{L(N.m)} = Lever Torque in Newton metres, N.m.

F_{(N) }= the force applied in Newton, N.

D_{(m) }= Distance from the pivot point to the point where the force is applied in metres, m.

1. A lever is used to lift a heavy rock. If a force of 200N is applied at one end of a 2.5-metre long lever, with the fulcrum located at the opposite end, calculate the torque exerted by the lever to lift the rock.

Given: F_{(N)} = 200N, D_{(m)} = 2.5m

Lever Torque, T_{L(N.m)} = F_{(N)} * D_{(m)}

T_{L(N.m)} = 200 * 2.5

T_{L(N.m)} = 500N.m.

2. A mechanic uses a lever to turn a stubborn bolt. The torque needed to turn the bolt is 120N.m. If the mechanic applies a force at a point 0.4 metres from the pivot, calculate the force the mechanic needs to apply.

Given: T_{(N.m)} = 120N.m, D_{(m)} = 0.4m

Lever Torque, T_{L(N.m)} = F_{(N)} * D_{(m)}

F_{(N)} = T_{L(N.m)} / D_{(m)}

F_{(N)} = 120/ 0.4

F_{(N)} = 300N.
