## 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, TL(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, TL(N.m) = F(N) * D(m)

TL(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.

Lever Torque Calculation:

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, TL(N.m) = F(N) * D(m)

TL(N.m) = 200 * 2.5

TL(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, TL(N.m) = F(N) * D(m)

F(N) = TL(N.m) / D(m)

F(N) = 120/ 0.4

F(N) = 300N.
