Two people stand on a plank suspended in the air by two cables on either side of the plan. Suppose that, combined, the two people have a total weight of -1300 N. The tensions in the supporting ropes that support their scaffold add to +1700 N. The weight of the scaffold itself must be

In the figure, horizontal scaffold 2, with uniform mass m₂ = 34 kg and length L₂-2.2 m, hangs from horizontal scaffold 1, with uniform mass m₁-45 kg. A 18 kg box of nails lies on scaffold 2, centered at distance d-0.50 m from the left end. What is the tension T in the cable indicated? Number i Units 2 T=7

A uniform 34.0-kg beam of length { = 4.55 m is supported by a vertical rope located d = 1.20 m from its left end as in the figure below. The right end of the beam is supported by a vertical column. (a) Find the tension in the rope. N (b) Find the force that the column exerts on the right end of the beam. (Enter the magnitude.) |N

A uniform 50-kg scaffold of length 7.0 m is supported by two light cables, as shown below. A 70-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. mbucket = Tieft - Tright N N kg
