A 69.5 kg painter is on a uniform 30.0 kg scaffold supported from above by ropes . There is a 5.0 kg pail of paint to one side, as shown. The scaffold is 6 m long. 1.0 m on both ends and 4 m in the middle. From the left end at 1.0 m to the pail is 1.0 m.
How close to the end can he approach safely?

bobpursley,
first, sum vertical forces and set to zero.
second, sum moments about any point (it helps to choose where an unknown force operates, so that distance is zero), and set to zero
those two equations will allow you to solve it.

Kyle,
which end are you looking for?
