Question

A 16 cm long spanner used to produces a force equal to 40N. what will be the length of the spanner to produce a force of 80NA 16 cm long spanner used to produces a force equal to 40N. what will be the length of the spanner to produce a force of 80N.

Answer 1

Answer:

The spanner should be 8cm long

Explanation:

Pressure = Force/Area

16cm produces 40 N

Force increases when area decreases

Therefore, 40×2=80N

So Length = 16/2=8cm long spanner

But you should, instead of 'force', write 'pressure'. There is no way you can increase the force by changing the length of the object. You can change only the pressure.
