Question:
A painter is standing on the ladder (mass 40 kg and length 2.5 m) in Figure P8.30. There is friction between the bottom of the ladder and the floor with µS= 0.30, but there is no friction between the ladder and the wall. The painter has mass 70 kg and is standing a distance of 0.60 m from the top.?
(a) Make a sketch showing all the forces on the ladder. Be sure to show where each force acts.?
(b) Express the conditions for transnational and rotational equilibrium for the ladder.?
(c) If θ = 60°, use the results from part (b) And determine whether or not this ladder will slip.
