The person in the figure below weighs 165 lb. As seen from the front, each light crutch makes an angle of θ = 24.0° with the vertical. Half of the person's weight is supported by the crutches. The other half is supported by the vertical forces of the ground on the person's feet. A person is shown supporting their weight on a pair of crutches, one under each arm, such that their bottom ends are farther apart than their top ends. Each crutch forms an angle θ with the vertical. (a) Assuming that the person is moving with constant velocity and the force exerted by the ground on the crutches acts along the crutches, determine the smallest possible coefficient of friction between crutches and ground. Answer:........ (b) Determine the magnitude of the compression force supported by each crutch. Answer: .......lb
