# Torque on a hinge to a gate that is 69 inches long

• ewhite17
In summary, torque on a hinge is a measure of the rotational force applied to the hinge, calculated by multiplying the force applied to the hinge by the distance from the hinge to the point where the force is applied. To calculate torque on a hinge, you need to know the force applied to the hinge and the distance from the hinge to the point where the force is applied, using the formula: torque = force x distance. The unit of measurement for torque is newton-meters (Nm) in the metric system, or foot-pounds (ft-lb) in the imperial system. The length of a gate is directly related to the torque on a hinge, meaning that a longer gate will exert greater torque on the hinge. Torque on

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?

## 1. What is torque on a hinge?

Torque on a hinge is a measure of the rotational force applied to the hinge. It is calculated by multiplying the force applied to the hinge by the distance from the hinge to the point where the force is applied.

## 2. How do you calculate torque on a hinge?

To calculate torque on a hinge, you need to know the force applied to the hinge and the distance from the hinge to the point where the force is applied. The formula for torque is: torque = force x distance.

## 3. What is the unit of measurement for torque?

The unit of measurement for torque is newton-meters (Nm) in the metric system, or foot-pounds (ft-lb) in the imperial system.

## 4. How is torque on a hinge related to the length of a gate?

The length of a gate is directly related to the torque on a hinge. This means that the longer the gate, the greater the torque that will be exerted on the hinge.

## 5. Can torque on a hinge be adjusted?

Yes, torque on a hinge can be adjusted by increasing or decreasing the distance from the hinge to the point where the force is applied. This can be done by changing the position of the hinge or by adding or removing weight from the gate.
