Torque Calculator

Find torque from force, lever arm and angle.

Force (N)

Lever arm length

Angle (degrees)

Calculated Output

Torque (N·m) 15

Formula: τ = F × r × sin(θ)

Step-by-Step Breakdown

1. Values used:

2. Force = 50 N

3. Lever arm length = 0.3

4. Angle = 90 degrees

6. Torque = Force x Lever arm length = 50 x 0.3 = 15N·m

Did this calculator solve your problem today?

The math behind it

τ = force × lever arm × sin(angle). Maximum when the force is perpendicular (90°).

50 N at 0.3 m, 90° → 15 N·m.
