Question

A nut has been
tightened by a
force of 200 N
using 10 cm long
spanner. What length of
of a
spanner is required to loosen
the same nut with 150 N force?​

Answer 1

Answer:

13.3 cm

Explanation:

let us use the equation

torque = rxF

so the same torque will be required to open the

nut with 150 N force since the nut is the

same

torque=200*0.1=20Nm

now

20Nm=Fxr

20=150xr

r=20/150=4/30-0.133m=13.3cm
