This fulcrum calculator will help you pinpoint the ideal fulcrum location for your lever, no matter the lever class. It is pretty simple to use: Select the appropriate lever class from the Lever class list. Enter the correct values for the Load, Effort, and the Length of the lever fields.
This tool will calculate the torque generated around an axis by a force applied at right angle to a lever arm of a specified length, τ=Fr.
The Lever Torque Calculator is a useful tool for calculating torque in systems involving levers, which are commonly used in engineering, physics, and everyday tasks. Understanding how to calculate torque helps in optimizing designs, ensuring safety, and improving efficiency in mechanical systems.
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, T L(N.m) = F (N) * D (m) T L(N.m) = 200 * 2.5. T L(N.m ...
Describe how the magnitude of a torque depends on the magnitude of the lever arm and the angle the force vector makes with the lever arm. Determine the sign (positive or negative) of a torque using the right-hand rule. Calculate individual torques about a common axis and sum them to find the net torque.
Calculation Formula. The fulcrum force is calculated using the following equation: \ [ FF = EF + LF \] Where: \ (FF\) represents the fulcrum force in Newtons (N), \ (EF\) is the effort force applied in Newtons (N), \ (LF\) is the lever force, also in Newtons (N).
This lever mechanical advantage equation and calculator Case #1 will determine the force required for equilibrium with the known forces and length.
