Question

What force in newtons must be applied perpendicular to the end of a wrench handle 25 cm long to produce torque 500N *cm

Answer 1

20 N

Step-by-step explanation

Torque produced by a force F perpendicular to a lever arm with length r is:

`\tau=F\cdot r`

In this case we have to find F, when τ = 500 N*cm and r = 25cm:

Solving for F:

To produce a torque of 500N*cm, a perpendicular force of 20N must be applied
