How Does Distance Affect Torque While Maintaining the Same Force?

AI Thread Summary
Distance significantly affects torque, as torque is calculated by multiplying the force applied by the distance from the pivot point. When a force of 70 pounds is applied 1 foot from the nut, it generates a specific torque. If the same force is applied 3 inches from the nut, the torque produced is less because the distance is shorter, despite the downward force remaining constant. The distinction between torque and force is crucial, as they are defined differently; torque depends on both the magnitude of the force and the distance from the pivot. Understanding these principles clarifies how distance influences torque while maintaining the same force.

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.
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
Thread 'Beam on an inclined plane'
Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
