A painter wishes to know whether or not he can safely stand on a ladder. The ladder has a mass M₁ = 10 kg which is uniformly distributed throughout its length L = 6.1 m. The ladder is propped up at an angle theta = 61º. The coefficient of static friction between the ground and the ladder is mus = 0.31, and the wall against which the ladder is resting is frictionless. Ꮎ Calculate the maximum mass of the painter for which the ladder will remain stable when he climbs a distance d = 3.9 m up the ladder. f the painter does not stand on the ladder, what is the minimum angle theta for which the ladder will remain stable?

A uniform horizontal beam 5.00 m long and weighting 3.03 102 N is attached to a wall by a pin connection that allows the beam to rotate. Its far end is supported by a cable that makes an angle of 53.0° with the horizontal (Figure (a)). If a person weighing 6.05 102 N stands 1.60 m from the wall, find the magnitude of the tension in the cable and the force exerted by the wall on the beam. T = N Rx = N Ry = N Even if we selected some other axis for the torque equation, the solution would be the same. For example, if the axis were to pass through the center of gravity of the beam, the torque equation would involve both T and Ry. Together with Equations (1) and (2), however, the unknowns could still be found—a good exercise. In this example, notice the steps of the Problem-Solving Strategy could be carried out in the explicit recommended order.QUESTION What happens to the tension in the cable if the man in Figure (a) moves farther away from the wall?
