## Would it be possible for a small force to produce a larger torque than a large force explain your answer and give an example of when this might be true?

Since the torque involves the product of force times lever arm, a small force can exert a greater torque than a larger force if the small force has a large enough lever arm. The tension force in the bicycle chain can be assumed to be the same at both the front and rear sprockets.

How is it possible for a large force to produce a zero torque?

A torque is about an axis/point of rotation. The size of the force x distance the force acts (perpendicularly) from the axis determines the torque. If you choose the axis so that the force passes through it – the torques about this axis will be zero.

### Which force produces the larger torque?

The point or line about which an object turns is its center of rotation. For example, a door’s center of rotation is at its hinges. A force applied far from the center of rotation produces a greater torque than a force applied close to the center of rotation.

How can a large force still end up with a small amount of power?

So if an object has a very small velocity (not moving very far over time, even though a large force may be applied to it, the Power will remain small. Stepping on the gas, or “speeding up” the car, is applying a force which will increase velocity and increase power.

## How can a smaller force exert a greater torque than a larger force while acting on the same system?

ANSWER: Yes, a small force can exert a greater torque than a large force. Torque equals the product of the force and the lever arm distance. A force of 5.0 N with a lever arm distance of 3.0 m produces a torque of 15 m N. A 10 N force with a lever arm distance of 1.0 m produce a torque of 10.0 m N.

How can a small force produce a greater angular acceleration of a wheel than a large force?

Rotational Inertia: Force is required to spin the bike wheel. The greater the force, the greater the angular acceleration produced. The more massive the wheel, the smaller the angular acceleration. If you push on a spoke closer to the axle, the angular acceleration will be smaller.

### Can the torque of small force be large?

As long as the small force has a large moment arm (long lever), it can create a large torque. The torque is basically defined to be the distance times the force. As long as the distance is large enough, a tiny force can create a torque as large as you like.

What is a small force?

Small masses generally exert small forces, which generally result in small accelerations (changes in motion).

## How can power developed be increased in doing work?

Power is the rate at which work is done or energy is transferred in a unit of time. Power is increased if work is done faster or energy is transferred in less time.

As long as the distance is large enough, a tiny force can create a torque as large as you like. Can a small force exert a greater torque than a larger force? Sure, remember that a torque is a force acting at a distance – so a longer moment arm (distance) multiplies what ever force is applied.

### What is torque and how does it work?

It’s all about leverage. As long as the small force has a large moment arm (long lever), it can create a large torque. The torque is basically defined to be the distance times the force. As long as the distance is large enough, a tiny force can create a torque as large as you like.

What happens when a large force is applied through the center?

A large force, applied through the center of gravity, produces no torque. Remember what a torque (or moment) is: two equal and opposite parallel forces. Also remember that a torque or moment can be applied anywhere on a rigid body with changing the equilibrium calculation. Why is healing the inner child so important?

## Does torque depend on the center of mass of a body?

Yes. A force applied on the center of mass of a body does not produce torque around this center of mass.
