A ladder AB is supported by a smooth vertical wall and a rough horizontal floor. A boy moves very slowly from A to B while the ladder remains at rest. Which statements are correct?
Options:(select one or more)
Answer:
A, C, D
Solution:
Vertical equilibrium keeps the floor normal equal to the total weight, independent of the boy’s position and the ladder’s uniformity.
Horizontal equilibrium makes floor friction equal to the wall reaction. Taking moments about A shows the wall reaction increases as the boy moves toward B.
