Serway & Jewett β Static Equilibrium and Elasticity: Problem 40
A stepladder of negligible weight is constructed as shown in Figure P12.40, with \(AC = BC = \ell = 4.00 \text{ m}\). A painter of mass \(m = 70.0 \text{ kg}\) stands on the ladder \(d = 3.00 \text{ m}\) from the bottom. Assuming the floor is frictionless, find (a) the tension in the horizontal bar \(DE\) connecting the two halves of the ladder, (b) the normal forces at \(A\) and \(B\), and (c) the components of the reaction force at the single hinge \(C\) that the left half of the ladder exerts on the right half. Suggestion: Treat the ladder as a single object, but also treat each half of the ladder separately.
