One end of a uniform meter stick is placed against a vertical wall. The other end is held by a lightweight cord that makes an angle ? with the stick. The coefficient of static friction between the end of the meter stick and the wall is 0.400.  What is the maximum value thetheta can have if the stick is to remain in equilibrium?

One end of a uniform ℓ = 4.40-m-long rod of weight w is supported by a cable at an angle of ? = 37° with the rod. The other end rests against a wall, where it is held by friction (see figure). The coefficient of static friction between the wall and the rod is ?s = 0.570.  Determine the minimum distance x from point A at which an additional weight w (the same as the weight of the rod) can be hung without causing the rod to slip at point A._______________________ m

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 µ = 0.385, determine the smallest angle the ladder can make with the floor without slipping.

As part of an engineering design, a load of mass M2=10 kg is to be suspended from the far end of a beam of mass M1=8kg. A horizontal cable supporting the beam attaches to the beam at a distance of d=2m from a joint/hinge. The length of the beam is L=7m. The beam makes an angle of 55 degrees with the horizontal.

A 3.0-m-long ladder leans against a wall at an angle of 60° with respect to the floor. What is the minimum value of μs , the coefficient of static friction with the ground, that will prevent the ladder from slipping? Assume that friction between the ladder and the wall is negligible.

One end of a uniform rod of weight w = 73.5 N and length L = 2.55 m is supported by a cable at an angle of ? = 37.0°above the rod. The other end rests on a small frictionless support and presses into a wall as shown in the figure.
