A stepladder of negligible weight is constructed where x = 1.80 m. A painter of mass 63.0 kg stands on the ladder 3.00 m from the bottom.
Assuming the floor is frictionless, find the following. (Suggestion: Treat the ladder as a single object, but also each half of the ladder separately.)
(a) the tension in the horizontal bar connecting the two halves of the ladder
N
(b) the normal forces at A and B
N (at A)
N (at B)
(c) the components of the reaction force at the single hinge C that the left half of the ladder exerts on the right half
N (rightward component)
N (upward component)
I do not know how to start this problem but i know that for (b) both forces should add up to 617.4
