A ladder of length 5 m is resting against a smooth wall, its point of contact being just below a first floor window. The bottom of the ladder rests on the ground and the coefficient of friction between the ladder and the ground is 0.3. A person of mass 75 kg climbs the ladder, which has a mass of 4 kg. The bottom of the ladder is at the point of slipping, outward from the wall, just as the person reaches the mid-point of the ladder’s length. Draw a free body diagram of the ladder and calculate the maximum frictional force opposing the slipping motion. In addition, determine the angle of inclination (θ) of the ladder, when the person is at the mid-point and the ladder is on the verge of slipping.

A 150lb man stands on a 60lb bar to which a cable is fixed at B. The cable passes over two fixed pegs with coefficients of friction indicated. Assume that the arrangement of the pegs permits the cable to contact each peg over a total angle of 90-degrees (90-degrees per peg). Assume that the normal force exerted by the man on the bar acts downward through A. Find the largest force the man can exert on the cable and maintain the bar horizontal.
