We have three methods for calculating torque about a particular point. R θ Force acts here. F Force acts here. R Force acts here. Use this method if both R and θ are easy to find. Use this method if the lever arm is easy to find. Use if Rr and Fr are easy to break into components.

The ability of a force to rotate an object about an axis is called torque. Experiments indicate that the rod in the figure is balanced if r1 F1 = r2 F2. This suggests that torque = r⊥ F, where r⊥ (referred to as lever arm) is the perpendicular distance from the location of force to the pivot.
Calculating torque (1) Choose a sign convention (e.g. anti-clockwise +ve), then decide in which direction force is pulling or pushing lever. Write that sign in front of your answer. Method 1: If you're given r and θ, use formula for torque (magnitude) τ = r F sinθ (Note: sinθ = sinφ, ∴ it doesn’t matter which angle you use)
