Why is a long spanner better than a short spanner?

Better to use a long spanner rather than a short one to tighten a nut on a bolt:- The lower the force required to achieve the given torque, the longer the spanner. This means the fastener’s side load is minimised. This reduces the risk of damage and allows for more precise torque readings.

Why it is easier to open a tight bolt with a spanner having a long handle?

A long handle increases the torque and it is easier to open a tight bolt by applying a little force. Easier to open a tight bolt with a spanner having a long handle:- Longer spanners provide the lever (= spanner) more mechanical advantage, making it easier to tighten to the proper torque – or undo.

Why are long spanners used?

(i) Spanner has a long handle to produce larger turning moments when a small force is applied at the handle end. (ii) The steering wheel is of large diameter to decrease the amount of force required to produce the turning effect.

Why does using a wrench make it easier to loosen a bolt?

A long handled wrench makes it easier to unscrew tight bolts. This is because we increase the torque by moving the applied force further from the turning point. Note, it is only the perpendicular component of the force acting on the lever that produces torque.

How does the long handle make it easier to loosen the nut?

Long handle sparner will minmize the force which is applied in loosenig the nut since moment remains the same.

What kind of advantage does a longer spanner gave in loosening a tight nut?

A longer wrench provides more torque to overcome the resistance of the rusted nut/bolt.

When a nut and bolt are difficult to undo it is easier to turn the nut by using a longer spanner because the longer spanner gives?

If a nut is difficult to undo with a short spanner, a longer spanner will help. This is because there will be a bigger moment on the nut, when the same force is applied further from the pivot.

Which wrench will make it easier to tighten the bolt?

An adjustable wrench, also called an adjustable spanner or an adjustable crescent is a tool, which can be used to loosen or tighten a nut or bolt. It has a “jaw” (the part where the nut or bolt fits), which is of adjustable size [source: Websters].
