Understanding Torque: Solving a Wrench Homework Question

In summary, torque is the measure of a force's ability to cause rotational motion and is important to understand in physics and real-world situations. To calculate torque, you multiply the force applied by the distance from the pivot point. The unit of measurement for torque is typically newton-meters or foot-pounds. The direction of the force affects torque because it is a vector quantity. One example of calculating torque is when using a wrench to loosen a bolt, where the torque would be 10 newton-meters for a force of 20 newtons applied at a distance of 0.5 meters.

I think it's talking about the force applied on the points of the bolt.That is,it's distance must be the radius and we know the torque.So we can find the force.
 

1. What is torque and why is it important to understand?

Torque is the measure of a force's ability to cause rotational motion. It is important to understand because it is a fundamental concept in physics and is applicable in many real-world situations, such as using tools, driving a car, or playing sports.

2. How do I calculate torque?

Torque can be calculated by multiplying the force applied to an object by the distance from the pivot point to the point where the force is applied. The formula is T = F x d, where T is torque, F is force, and d is distance.

3. What is the unit of measurement for torque?

Torque is typically measured in units of newton-meters (N·m) in the metric system or foot-pounds (ft·lb) in the imperial system.

4. How does the direction of the force affect torque?

The direction of the force applied to an object affects torque because torque is a vector quantity. This means that the direction of the force must be taken into account when calculating torque. For example, if the force is applied perpendicular to the lever arm, it will produce the maximum torque, while a force applied parallel to the lever arm will produce no torque.

5. Can you provide an example of calculating torque?

Sure, let's say you are trying to loosen a bolt with a wrench. The force you apply to the handle of the wrench is 20 newtons and the distance from the pivot point to the point where you apply the force is 0.5 meters. To calculate the torque, you would use the formula T = F x d, so T = 20 N x 0.5 m = 10 N·m. This means that the torque you are applying to the bolt is 10 newton-meters.
