What is the minimum value of the coefficient of static friction that prevents the ladder from slipping?A ladder of mass M and length L = 4m is on a level floor leaning against a vertical wall. The coefficient static friction between the ladder and floor is mus = .6 while the friction between the ladder and the wall is negligible. The ladder is at an angle of 50 degrees above the horizontal. A man of mass 3M starts to climb the ladder. To what distance up the ladder can the man climb before the ladder starts to slip on the floor ? x =
- A ladder, mass 50kg, 6m long is leaning so that it makes a 20° angle with a smooth wall. A student wants to climb the ladder so that his centre of mass will be 2/3rd of the way up. If the students mass is 100kg find the normal force from the wall. Will this much force from the wall cause the ladder to slip sideways if the coefficient of static friction at the floor is 1.0?A 10 m long uniform board weighing 400 N is supported by ropes at each end. A worker weighing 900 N stands 3.0 m from the rope on the left. Determine the tension in the two ropes for static equilibrium.help
- Modelled after problem 5 in the Problems_Torque_Statics: A 12.83-m-high and 19.48-m-long wall under construction and its bracing are shown in the figure. The wall is in stable equilibrium without the bracing but can pivot at its base. Calculate the force exerted by each of the 10 braces if a strong wind exerts a horizontal force of 871.28 N on each square meter of the wall. Assume that the net force from the wind acts at a height halfway up the wall and that all braces exert equal forces parallel to their lengths. Neglect the thickness of the wall. The angle between the braces and the wall is as shown in the figure as 35 degrees.A 12.0 kg monkey climbs up a 135 N uniform ladder of length L leaning against the wall at an angle of 25°. The upper end of the ladder has a coefficient of friction of 0.25 and lower end of the ladder rests on a frictionless surface, but the lower end is attached to the wall by a horizontal rope that can support a maximum tension of 120 N. (a) Find the tension in the rope when the monkey is one third of the way up the ladder. (b) Find the maximum distance d (expressed as a fraction of L) that the monkey can climb up the ladder before the rope breaks.A ladder leans against the wall, as shown in the diagram below. The base of the ladder is resting at an angle on a frictional surface.(The wall against which the ladder leans is essentially treated as frictionless). The angle in orientation presented above is at its maximum–if the angle were to be any less, the ladder would slip and fall to the ground. Ladder Mass=5.0kg Ladder Length=2.0m Angle=60° Complete the free-body diagram for all forces acting upon the ladder in its current orientation. Draw force vector arrows sourced from their point of contact , provide force vector arrows with labels and magnitudes, and ensure they are drawn in appropriate relative proportion with regards to one another. What is maximum coefficient of static friction in this instance? (A)About 0.22 (B)About 0.35 (C)About 0.48 (D)About 0.58

B) If the ladder is just on the verge of slipping when the firefighter is 9.20 m from the bottom, what is the coefficient of static friction between ladder and ground? C) What If? If oil is spilled on the ground, causing the coefficient of static friction to drop to half the value found in part (b), what is the maximum distance (in m) the firefighter can climb along the ladder from the bottom before the ladder slips?One end of a uniform beam of length L=3mandweight 185 Nis connected to a vertical wall with a cable.
