Question
Can someone please help me to solve the following question showing all needed work and formulas along with needed diagrams. Please and thank you!
2. The ladder shown is supported by a horizontal floor and a vertical wall. It is 16 ft long,
weighs 48 lb (assumed to be concentrated at its mid-length), and supports a person
weighing 200 lb at point D. The vertical wall is smooth and offers no frictional resistance.
The coefficient of static friction between the ladder and the floor is 0.35.
Show free-body diagram(s)
a) Determine the smallest angle that the ladder can make with the floor before
slipping begins.
b) Determine the frictional force between the floor and the lower end of the ladder.
