We are given

the torque requirement of 97 Newton meter.

The formula of the torque is

τ = r * F * sinθ

where

τ is the torque
r = radius from the axis of rotation to the point of application.
F = force exerted
θ = the angle between the lever arm and the radius

Try to substitute the given and solve for F.
