What is the torque at the end of the bar?

To determine the torque at the end of a bar, you need to know the force applied and the distance from the pivot point to the point where the force is applied. Torque is calculated using the formula τ = r × F × sin(θ), where τ is the torque, r is the distance from the pivot point, F is the applied force, and θ is the angle between the force vector and the lever arm. If the force is applied perpendicularly, sin(θ) equals 1, simplifying the equation to τ = r × F.
