A 65 kg person stands 2.5 m away from the left end of a uniform 4 m long scaffold of mass 80 kg. Vertical ropes at each end support the scaffold. Find the tensions in the ropes.
Added by Jaime H.
Step 1
First, we need to find the total weight of the person and the scaffold. The weight of an object is its mass times the acceleration due to gravity. We'll use 9.8 m/s^2 for the acceleration due to gravity. So, the total weight is (65 kg + 80 kg) * 9.8 m/s^2 = 1422 Show more…

A 130 kg scaffold is 6.40 m long. It is hanging with two wires, one from each end. A 560 kg box sits 1.00 m from the left end. What is the tension in the left hand side wire?

A person is standing on a section of uniform scaffolding as shown in the figure. The section of scaffolding is L = 1.50 m in length, has a ms = 21.0 kg mass and is supported by three ropes as shown. Determine the magnitude of the tension in each rope when a person with a weight of Wp = 720 N is a distance d = 0.700 m from the left end.

A uniform plank of length 2.00 $\mathrm{m}$ and mass 30.0 $\mathrm{kg}$ is supported by three ropes as indicated by the blue vectors in Figure $\mathrm{P} 12.25 .$ Find the tension in each rope when a $700-\mathrm{N}$ person is $d=0.500 \mathrm{m}$ from the left end.
