Best Answer

you will 'exert' a torque of (30*0.85)N.m at the hinges = 25.5N.m

The idea is to use the definition of a torque, and simply multiply the force, times the distance from the axis of rotation.

What happens to the distance over which you exert your force?

Nothing particular happens specifically to the distance.


Can small force exert greater torque?

Not exactly,torque is the force that affects rotational motion; the greater the torque, the greater the change in rotational motion. It is always specified with regard to the axis of rotation.


Can a small force ever exert a greater torque than a larger force?

Of course. Torque is the product of the (force) times (its distance from the axle). If the force you have doesn't produce enough torque, you simply apply the same force farther from the axle, and that increases the torque. That's why, if you can't crack the nut with the wrench you have and the strength you have, you slip a piece of pipe over the handle and make the wrench look twice as long. In that way, you have temporarily transformed the wrench into a "Persuader", and the nut is highly likely then to be persuaded. If you can arrange for the small force to be exerted at a long enough distance from the axle, it can apply as much or more torque than the larger force can when applied closer in.


Can charged bodies exert forces even at a distance?

Yes. The gauge particles for the electromagnetic force are (massless) photons, so there's no distance limit to electromagnetic interactions.


Can a small force produce a greater torque than a large force?

Can a small force ever exert a greater torque than a larger force? Explain yes it is possible if small force is applied with a larger moment arm(lever arm) as compared to larger force.

Why does a screwdriver allow you to turn a screw you couldn't turn by hand?

A screwdriver allows you to exert more torque on a screw. Torque is defined as the product of the force exerted and the distance from the center of rotation. Torque is essentially a rotational force. It is simple to increase torque, simply increase the distance from the center that the force is being applied, and there is greater torque without increasing your effort. The handle is made to be wide, so that a greater torque can be exerted. It is also much easier to grip a screwdriver than it is to grip a screw. That also plays a factor.


What would one use a hydraulic torque wrench for?

Hydraulic torque refers to a tool that is designed to exert torque on a fastener to achieve the desired tightening or loosening of connection by using a hydraulic.

Does a bar magnet exert a torque on itself due to its own magnetic field?

electric motors produce torque so in the sense yes


Why would you choose a bigger handle of a screwdriver?

Because your hand can get a better grip and exert more torque or pressure.


3 ways simple machines make work easier?

Machines make work easier by: -Changing the amount of force you exert -Changing the distance in which you exert your force -Changing the direction in which you exert your force


When do you do work?

when you exert a force on an object that causes the object to move some distance.

Explain how machines make work easier if they do not decrease the amount of work you need to do?

A machine makes work easier by changing the amount of force you exert, the distance over which you exert your force, or the direction in which you exert your force.


You do on an object when you exert a force on the object that causes the object to move some distance?

You do work


When a simple machine increases the force you exert what other factors change?

The distance of the object
