- A uniform 37.0 kg scaffold of length 6.4 m is supported by two light cables, as shown below. An 82.0 kg painter stands 1.0 m from the left end of the scaffold, and his painting equipment is 1.3 m from the right end. If the tension in the left cable is twice that in the right cable, find the tensions in the cables (in N) and the mass of the equipment (in kg). I don't understand how to find mass of the equipment.Please asapA beam of mass 40.0 kg is supported by a cable and attached to a wall as shown in picture. Find the tension T int the cable and the magnitude of force ,F exerted by the wall on the beam.
- A uniform 50-kg scaffold of length 7.0 m is supported by two light cables, as shown below. A 61-kg painter stands 1.0 m from the left end of the scaffold, and his paint bucket is 1.5 m from the right end. If the tension in the left cable is twice that in the right cable, find the tensions in the cables and the mass of the bucket. m bucket = kg T (left) = N T (right) = NA traffic light hangs from a pole as shown. The uniform aluminum pole AB is 7.50 m long and has a mass of 12.0 kg. The mass of the traffic light is 21.5 kg.

- An elastic rope is stretched between the tops of two identical posts. A man is to walk along the elastic rope. When the man is at the middle of the elastic rope, the tension in the elastic rope is 2220 N. Each half of the elastic rope makes an angle of 8.00with respect to the horizontal. Find the weight of the man.A 129N tightrope walker stands at the center of the rope such that each half of the rope makes an angle of 5 degrees with the horizontal. What is the tension in the rope?Rope A lies in the +x direction and rope B is 120o counterclockwise from rope A (they are tied together at the origin). Rope C is also attached to rope A and B at the origin. If rope A has 3.0 units of force, and rope B is pulling with 5.0 units of force, how many units of force, and in what direction must rope C pull to balance and create a static equilibrium with the other two ropes?
