A ladder rests on the floor of a room, leaning agains a wall. If the coefficient of static friction between the ladder the floor is `mu_(f)` and that between ladder and is `mu_(w)`, what is the minimum angle `theta` that the ladder can make with the floor if the ladder is not to slip? Assume that the mass of the ladder is distributed uniformly.

A light ladder rests onn te rough floor of a room, leaning against a smooth wall. The ladder touches the wall at height h above the floor. A man climbs up the ladder until the base of the ladder is on the verge of slipping. The coefficint of static friction between the foot of the ladder and floor is mu . (a) What is the horizontal distance moved by the man? (b) Solve part (a) if the ladder is uniform and has the same weight as the man and the base of the ladder is at a distance l from the wall.

In the figure, a ladder of mass m is shown leaning against a wall. It is in static equilibrium making an angle theta with the horizontal floor. The coefficient of friction between the wall and the ladder is mu_1 and that between the floor and the ladder is mu_2. the normal reaction of the wall on the ladder is N_1 and that of the floor is N_2. if the ladder is about to slip. than

In Fig. 7.149 , coefficient of friction between the block and the floor is mu . Force F that will move the block on the floor with a uniform speed is :

A ladder of length l and mass m is placed against a smooth vertical wall, but the ground is not smooth. Coefficient of friction between the ground and the ladder is mu . The angle theta at which the ladder will stay in equilibrium is

A uniform ladder of length l rests against a smooth, vertical wall (figure). If the mass of the ladder is m and the the coefficient of static friction between the ladder and the ground is mu_(s) = 0.375 and the minimum angle theta_(min) at which the ladder does not slip. A uniform ladder at rest, leading against a smooth wall. Th ground is rough.

The friction coefficient between the board and the floor shown in figure is mu Find the maximum force that the man can exert on the rope so that the board does not slip on the floor

A ladder of length 5 m is placed against a smooth wall as shown in figure. The coefficient or friction is mu between ladder and ground. What is the minimum value of mu , If the ladder is not to slip?

If a ladder weighting 250 N in placed a smooth vartical wall having coefficient of friction between it and floor 03, then what is the maximum force of fraction available at the point of contact between the ladder and the floor?
