The person in the figure below weighs 167 lb. Each crutch makes an angle of θ = 26.0∘ with the vertical (as seen from the front). Half of the person's weight is supported by the crutches, the other half by the vertical forces exerted by the ground on his feet. Assuming he is at rest and the force exerted by the ground on the crutches acts along the crutches, determine each of the following. (a) the smallest possible coefficient of friction between crutches and ground (b) the magnitude of the compression force supported by each crutch Ib

As shown in the figure below, a uniform beam is supported by a cable at one end and the force of friction at the other end. The cable makes an angle of θ = 30∘, the length of the beam is L = 4.00 m, the coefficient of static friction between the wall and the beam is μs = 0.580, and the weight of the beam is represented by w. Determine the minimum distance x from point A at which an additional weight 2w (twice the weight of the rod) can be hung without causing the rod to slip at point A. x = m

A hungry bear weighing 735 N walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam (see the figure below). The beam is uniform, weighs 200 N, and is 5.50 m long, and it is supported by a wire at an angle of θ = 60.0∘. The basket weighs 80.0 N. (1) (a) Draw a force diagram for the beam. (Submit a file with a maximum size of 1 MB.) Choose File no file selected This answer has not been graded yet. (b) When the bear is at x = 1.20 m, find the tension in the wire supporting the beam. N When the bear is at x = 1.20 m, find the components of the force exerted by the wall on the left end of the beam. (Assume the positive +x direction is to the right and the positive +y direction is upward. Include the sign of the value in your answer.) Fx = N Fy = N (c) If the wire can withstand a maximum tension of 800 N, what is the maximum distance the bear can walk before the wire breaks? m

One end of a uniform 3.80-m-long rod of weight Fg is supported by a cable at an angle of θ = 37º with the rod. The other end rests against the wall, where it is held by friction as shown in the figure below. The coefficient of static friction between the wall and the rod μs = 0.450. Determine the minimum distance x from point A at which an additional object, also with the same weight Fg, can be hung without causing the rod to slip at point A.
