A 60.0 kg painter is on a uniform 25 kg scaffold supported from above by ropes. There is a 4.0 ? kg pail of paint to one side. Can the painter walk safely to both ends of the scaffold? If not, which end(s) is dangerous, and how close to the end can he approach safely?
If both ends of the scaffold are supported by ropes then there is no chance of the plank rotating. OHS would still complain about the lack of handrails, the fact that the plank can swing without stabilization. Not to mention that ropes are unacceptable. They should be Nylon woven tape with fixed ends and at very least a one tonne rating. However that is not the thrust of your question. If the ropes are NOT at the very ends then by passing the rope on the end which has the 4 kg can of paint the whole plank may rotate about the pivot created by the rope. This will depend on where the two ropes are on the plank.

missing data. How much tension can each rope sustain, how much tilt will the scaffolding undergo through movement. You have to be missing some data, that question is unanswerable too many variables.
