# Calculating Torque to Turn a Rod

• kenn6752
In summary, to calculate torque to turn a rod, you will need to know the force applied to the rod and the length of the rod. Torque is typically measured in newton-meters (N*m) or foot-pounds (ft*lb). Friction can affect the torque required to turn a rod by creating resistance against the motion of the rod. The length of the rod can also impact the torque required, with longer rods requiring more torque and shorter rods requiring less. Other factors such as weight, angle, and material can also affect the torque needed to turn a rod.

I am working on a senior design project, and we need to calculae the torque needed by a DC motor to turn a threader rod. Any ideas as to how to calculate the torque needed to turn a rod? .75" Diam., 1ft length, will be lifted/lowered up and down at 90° to level ground. I know I'm new, but any help is appreciated!

Any torque will turn a rod overcoming friction, how much is the question?

## 1. How do you calculate torque to turn a rod?

To calculate torque to turn a rod, you will need to know the force applied to the rod and the length of the rod. The formula for torque is torque = force x distance. Therefore, to calculate torque, you will multiply the force applied to the rod by the length of the rod.

## 2. What unit is torque measured in?

Torque is typically measured in newton-meters (N*m) or foot-pounds (ft*lb). These units represent the amount of force and distance used in the calculation of torque.

## 3. How does friction affect the torque required to turn a rod?

Friction can affect the torque required to turn a rod by creating resistance against the motion of the rod. This resistance will require more force to overcome, thus increasing the torque needed to turn the rod.

## 4. Can the length of the rod impact the torque required to turn it?

Yes, the length of the rod can impact the torque required to turn it. A longer rod will require more force to turn it, resulting in a higher torque value. Similarly, a shorter rod will require less force and have a lower torque value.

## 5. What other factors can affect the torque required to turn a rod?

In addition to friction and length, the weight of the rod, the angle at which it is being turned, and the material of the rod can also affect the torque required. Heavier rods, larger angles, and more rigid materials may require more torque to turn.
