What is a retaining nut in plumbing?
A retaining nut could be the packing gland nut on a valve stem or the nut used on a flare or compression fitting
What is the meaning of spanner?
One who, or that which, spans., The lock of a fusee or carbine; also, the fusee or carbine itself., An iron instrument having a jaw to fit a nut or the head of a bolt, and used as a lever to turn it with; a wrench; specifically, a wrench for unscrewing or tightening the couplings of hose., A contrivance in some of the ealier steam engines for moving the valves for the alternate admission and shutting off of the steam.
What nut is used in the manufacturing of dynamite?
Peanut oil is sometimes used in the manufacturing of nitroglycerin.
Which tool is sometimes called a nut driver it is used to tighten nuts is the some way that a screwdriver tighten screw?
A wrench is used to tighten nuts. Socket wrenches are a type of nut driver.
Are a nuts and bolts screws?
No. A nut and bolt are a matched set of fasteners. The bolt goes into or through the object it will secure, the nut is spun on to the bolt and snugged up tight to complete the fastening. A screw is a single fastener driven into (usually) wood - there is no nut used with it. There are also screws for use in metal, but they do not hold as securely as a nut and bolt.
What does a spanner nut look like?
Exactly the same as any other nut. Spanner is just British terminology for wrench.
How do you calculate spanner size for nut?
How to calculate spanner size regarding bolts and nuts
Why you use the long spanner to open the rusted nut bolt?
you use a spanner to open a rusted nut bolt because you need a strong tool to open a rusted nut bolt.
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 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 metal nuts are made hexagonal type?
Because they are easier to make, a hexagonal bar can be held in a self centering 3 jaw chuck of a capstan lathe. Also they allow a spanner to to be put on them in 6 positions instead of 4 as with a square nut, making it easier to tighten or loosen them in a confined space.
Why is it easy tight a nut using a spanner of long arm than of a short arm spanner?
A long-arm spanner provides greater leverage, making it easier to apply more force to the nut with less effort. This increased leverage allows the user to generate more torque, which makes it easier to tighten the nut effectively. Conversely, a short-arm spanner provides less leverage, requiring more effort to generate the same amount of torque.
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.
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 a mechanic would choose a long spanner to undo a tight nut?
The mechanic would get more leverage. The rotational force applied to the nut is greater the longer the spanner, assuming the mechanic applies the same amount of force.
How do you remove rear brake drum 0n 1997 gmc?
Is it heavy duty model with axle bolts? If so, Remove axle bolts Slide axle out of differential housing use spanner wrench to loosen spanner nut (or hammer and chisel) Remove spanner nut and seal Drum should slide off
What is the action of a torque spanner?
A torque spanner attempts to infer the tension forces applied to a bolt, by measuring the turning force applied to the nut. This method suffers from uncertainties in the friction between the nut and the bolt, and again from the nut and the surface. It is necessarily an indirect measurement. It is vital that all surfaces be very clean and smooth for this method to be reliable. Compressible washers are a more reliable device, but less simple. Sometimes of a cone or a wave form.
