A uniform pole is propped between the floor and the ceiling of a room. The height of the room is 7.51 ft, and the coefficient of static friction between the pole and the ceiling is 0.667. The coefficient of static friction between the pole and the floor is greater than that between the pole and the ceiling.

What is the length of the longest pole that can be propped between the floor and the ceiling (in feet)?

A uniform ladder of length L and weight w is leaning against a vertical wall. The coefficient of static friction between the ladder and the floor is the same as that between the ladder and the wall. If this coefficient of static friction is μs = 0.370, determine the smallest angle the ladder can make with the floor without slipping. ° Please show work thank you
