Turning force (Moment) measured in Newton metres is equal to Force (Newtons) multiplied by Distance (metres).
Or to put it mathematically: Moment (Nm) = Force (N) x Distance (m)
The larger the distance the greater the moment.
The greater the force the greater the moment.
The greater the distance the smaller the force needs to be.
This means that a long screwdriver will prise open a paint can lid much easier than a coin will. This also means that a longer spanner will unscrew a nut easier than a small one (or indeed your hands).

Why do we use a spanner not our fingers to unscrew a nut?
Because a spanner provides extra leverage - and is much tougher than our fingers !
Why moment of inertia is also called rotational inertia?
Because it is a measure of the "resistence" of an object to be accelerated in its rotation. An object with a big moment of inertia is more difficult to increase/decrease its angular velocity (speed of rotation), than an object with a low moment of inertia.
What is the meaning of inferring in science?
this using what you know(facts obtained) and what occurs at that moment to draw conclusions on specific topic...
What is an example sentence using glanced?
Luckily, the stray bullet just glanced off of my skull. The teacher glanced up for just a moment.
What are the disadvantages of using a fixed-time period ordering system?
large safety stocks increase holding cost
Why is it easier to loosen a tight nut using a long spanner?
because spanner has a longer moment arm and torque depends upon moment arm greater the moment greater will be the torque produced so it is easy to unscrew a tight nut using longer spanner
Why does a long spanner make it easier to loosen a stuck nut than a short spanner?
This answer is based on simple mechanics. A spanner is a tool which you use to apply a twisting force on a nut. This twisting force is called a Moment. The equation for a moment: moment = force x distance of application As the force given by your arms will not increase just by using a bigger spanner, the size of the moment is directly related to the distance away from the nut the force is applied. So with a short spanner, say 30cm (0.3 metres) long and a typical force from your arm of about 100N (about 10kg) the moment will be: Moment = 100 x 0.3 = 30 Nm Now if a bigger spanner is used, say 50 cm (0.5 metres) long the moment is: Moment = 100 x 0.5 = 50 Nm So you can see if you use a bigger spanner, you are putting a larger twisting force upon the nut, so it it easier to loosen.
How do you increase the turning pressure on a spanner?
Fit a length of pipe over it to make it longer.
What material is used to make a spanner?
Usually steel, alloyed with vanadium(to increase springiness) and chromium(to increase hardness and resistance to wear)
How do you increase stiffness of a cantilever beam?
Increase the moment of inertia
When calculating moment of force what two changes can be made to increase the size of the moments?
1. increase the force2. increase the distance from the force to the point of moment
A spanner is used to tighten a nutAforce of 100n is applied 0.2 m from the center of the nut What is the moment?
20 Nm. You just multiply them together.
What increase the moment of inertia?
A rotating body that spins about an external or internal axis (either fixed or unfixed) increase the moment of inertia.
What is a sentence for spanner?
Pass me the spanner please.Tom bought a new spanner today.
