SUMMARY

The discussion centers on calculating the torque required for a torsion spring to lift a 69-inch gate that requires 50 lbs of force at a little over a 90-degree angle. The torque can be calculated using the formula: Torque (foot-pounds) = Force (lbs) x Distance (feet). In this case, the distance is 69 inches, which converts to 5.75 feet, resulting in a torque requirement of 287.5 foot-pounds to effectively lift or offset the weight of the gate. A free body diagram is recommended to visualize the forces acting on the gate.

PREREQUISITES
  • Understanding of torque and its calculation

I have a gate that is 69 inches long and it takes 50 lbs of force to lift at the end of the gate when it is extended at a little over a 90 degree angle. How many foot pounds of torque in a torsion spring will be needed to lift the gate or at least offset the majority of the weight?
