Question
(a) A uniform ladder of $300\text{N}$ rests agninst a smooth vertical wall and a rough horizontal floor making an angle of $60^{\circ}$ with the horizontal. Use the method of virtual work to find the frictional force between the foot of the ladder and the rough horizontal floor.
(b) Explain the following:
1. principal of virtual work.
2. D'Alembert's principle
3. Law of transmissibility
4. Virtual work
