How Does Distance Affect Torque While Maintaining the Same Force?

Click For Summary
SUMMARY

The discussion centers on the relationship between force and torque, specifically how applying the same downward force at different distances from a pivot point affects torque. Torque is defined as the product of force and the distance from the pivot point, which means that increasing the distance while maintaining the same force results in greater torque. For instance, applying a 70-pound force 1 foot from a nut generates less torque than applying the same force 3 inches away, due to the difference in lever arm length. This fundamental principle of mechanics clarifies why torque increases with distance from the pivot.

Question that’s been boggling my mind. If you have a 1 ft torque wrench and your tightening your wheels on you Car and apply a force of 70 pounds 1 ft from the nut I’m applying 70 pounds of downward force on the nut but applying a much larger torque to the nut. Now if I apply a 70 lb force 3” from the nut I am still applying 70 pounds of downward force on the nut so question is how can moving farther away apply a much bigger torque but still apply same downward force on the wheel and nut?

What is the definition of torque?

Much larger torque than what? You cannot compare a torque to a force.

Because that's how force and torque are defined. If they had the same definition, we wouldn't use two different names for them.
