- The person in Figure P5.6 weighs 170 lb. As seen from the front, each light crutch makes an angle of 22.0 with the vertical. Half of the persons weight is supported by the crutches. The other half is supported by the vertical forces of the ground on the persons feet. Assuming that the person is moving with constant velocity and 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 in each crutch.

She uses a scale to measure the tension in the rope as she changes the angle at which she pulls, while always keeping the 15 kg mass at exactly the same spot Compare the tension in the rope when it makes an angle of 30° with respect to the vertical with the tension in the rope when it makes an angle of 60° with respect to the vertical. Her friend, Zora, now takes an identical mass and attaches hers directly to the ceiling with just a rope. She attaches a second rope to the mass and pulls it until the first rope makes an angle of 0 = 20° with respect to the vertical, always keeping the second rope horizontal and the mass stationary.
