A. Determine the minimum coefficient of static friction between the ladder feet and the ground needed for the ladder to stay in rest.

B. Determine the magnitude of the normal force of the wall on the ladder.

C. Determine the magnitude of the normal force of the floor surface on the ladder.

D. Determine the magnitude of the force of friction between the floor and the ladder.

Answer #1

A ladder is leaning against a vertical wall, and both ends of
the ladder are at the point of slipping. The coefficient of
friction between the ladder and the horizontal surface is ?1 =
0.115 and the coefficient of friction between the ladder and the
wall is ?2 = 0.153. Determine the maximum angle with the vertical
the ladder can make without falling on the ground.

A ladder is leaning against a vertical wall, and both ends of
the ladder are at the point of slipping. The coefficient of
friction between the ladder and the horizontal surface is ?1 =
0.165 and the coefficient of friction between the ladder and the
wall is ?2 = 0.203. Determine the maximum angle with the vertical
the ladder can make without falling on the ground.

A ladder is leaning against a vertical wall, and both ends of
the ladder are at the point of slipping. The coefficient of
friction between the ladder and the horizontal surface is μ1 =
0.235 and the coefficient of friction between the ladder and the
wall is μ2 = 0.153. Determine the maximum angle with the vertical
the ladder can make without falling on the ground.

A ladder is leaning against a vertical wall, and both ends of the
ladder are at the point of slipping. The coefficient of friction
between the ladder and the horizontal surface is μ1 = 0.125 and the
coefficient of friction between the ladder and the wall is μ2
= 0.103. Determine the maximum angle with the vertical the ladder
can make without falling on the ground.

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.
