A 170. Lb. person is in crutches. Each crutch makes an angle of 22.0° with the vertical. Half of the person's
weight is supported by the crutches, the other half by
the vertical forces exerted by the ground onto his feet.
Assuming that he is at rest and that the force exerted
by the ground on the crutches acts along the crutches,
determine (a) the smallest possible coefficient of
friction between crutches and ground, and (b) the
magnitude of the compression force supported by
each crutch.
