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.


Why is it easy tight a nut using a spanner of long arm than of a short arm spanner?

The longer the arm of a spanner, the more leverage can be used. More leverage allows more pressure to be used against a nut to either tighten or to loosen.


How do you get the front differential plug off 2000 land rover discovery series 2?

The standard removal technique is to tap the bung with a hammer to loosen it and try to remove it with a single hex spanner or socket, if this does not work try to use a screwdriver in the centre at the same time as using the spanner. It is common for the bung to become stuck if it is done up too tight, if this is the case chisel the bung from the side. The bung will break in half and the tension will be released from the thread and the remainder will unscrew with your hand. If you do this you will obviously need to buy a new bung, I suggest you buy a brass one from a radiator shop. Katie


How do you change an auxiliary belt on a 206?

Loosen Tension Wheel centre bolt and un-adjust using 10mmm spanner.. this will allow removal of power steering belt. Loosen alternator bolts and un-adjust with 8mm adjusting bolt located at front /underside of alternator. fit new belt and tension using 8mm tensioning bolt,tighten tension wheel centre nut using 13mm socket, i use 13mm socket and mole grips as there is limited space, Replace power steering belt and tension using 10mm spanner , re tighten alternator holding bolts 15mm spanner4/socket. This was carried out on a Rover 216se. there may be more professional ways to carry out this repair, but it worked for me.....


How do you fix a leak in above ground vinyl pool liner at the main drain plug?

You can not turn gas adjustment nut on Remington baikal?

you can adjust the vent on the MP 153 using a spanner socket.


How do you increase the moment using a spanner?

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).

How do you adjust a meriva handbrake cable?

lift the corner of the offside car up and shove a prop arch lever for support. contact the dealer and ask for the vin number to ensure the correcr spanner width size for the head of the ratchet coller will collaborate. verify that the vin given by the dealer matches the actual car! then using a slider tray go beneath the car and look around the petrol tank. once checked for leaks in the tank are, its ok to then have a cigarette whilst working. using a ring spanner 13mm and an adjustable spanner size 15mm, wind one spanner clockwise and the other spanner the other clockwise way. once the cable becomes really slack, you;ll know you've been winding the wrong way like i did! once it becomes tight again, get someone to sit in the car and release the handbrake so that you can tighten it up further. once its done you can get out from underneath, start the car up and go for a drive to test out the adjustments please. job done.


How do you loosen tire bolts that are two tight?

Take it in and get a garage with an impact gun to remove them before you strip them and possibly cost yourself a rim. Try jacking up the car and putting it on a jackstand. Put the lug wrench on the lugnut, use the lugwrench to spin the wheel in the opposite direction of loosening then jerk the lugwrench the loosening direction using the momentum from the wheel to help you loosen it.


How do you install 88 Dodge Aries Alternator belt?

First you will want to loosen the alternator. To do this you will need to loosen the bolt holding adjustment bolt in place. This is right under the alternator. After loosening this bolt, you can use the adjusting bolt to loosen the alternator and the belt should slide right off. Then you can put on the new belt and tighten the alternator using the adjusting bolt. After the belt is to the proper tightness, tighten the bolt directly underneath the alternator to keep the belt tight and from becoming loose.
