The end of a light rope ABCD are connected to the same horizontal beam at A and D. Masses of 1 kg are suspended at B and C. AB = CD BC and AD = 2 AB. Calculate the tension in each part of the rope using the method of components if A and D are in the same horizontal plane (use g = 9.81 m/s2). A.

A ladder of weight W stands on a rough floor and rests against a frictionless wall, illustrated above. It is only stable if the angle between the ladder and the ground is greater than theta (theta > 60 degree). a. Find the coefficient of static friction between the floor and the ladder. b. A child of weight 4W places the ladder against the wall at angle 70 degree(theta = 70 degree). Calculate how far up the ladder it is safe for the child to climb.

A manager walks d = 3.4 m along a uniform plank supported by the floor at one end and by a vertical rope at the other, as in the figure. Find the tension in the rope if the plank's mass and length are M = 11 kg and L = 6 m, the manager's mass is m = 56 kg, and the angle = 21°.

A monkey of mass m = 10.0 kg is holding on to two vines each of length l = 3.00 m. The vines form an angle with the horizontal of 40.0 degrees (see figure). The monkey is not moving and the vines are considered massless and not stretchable.   a. What is the distance d between the mounting points of the vines at the top? b. Draw a free body diagram of the monkey and indicate all forces.
