You are on an elevator fixed to a wall that can move up and down freely while you pull with a force of 150 N on a massless rope (the orange line in the diagram below) with length L. This rope is connected to one end of a beam with the same length, L, and mass m=20 kg. The left end of the beam is in contact with the same wall the elevator is on and the coefficient of static friction =0.2 between the beam and the wall. See diagram below for a representation of the situation and note that free fall acceleration points directly downward L Part A) Label all the forces acting on the beam and discuss the direction of any torques exerted on the beam about the contact point between the beam and the wall Part B) What is the maximum angle the beam can subtend with respect to the horizontal _m such that it will just begin to slip? Potentially useful trig identities are sin(2x)=2sin(x)cos, sin(180-x)=sin(x), sin(90+x)=cos(x)

A ladder of length 5 m is resting against a smooth wall, its point of contact being just below a first floor window. The bottom of the ladder rests on the ground and the coefficient of friction between the ladder and the ground is 0.3. A person of mass 75 kg climbs the ladder, which has a mass of 4 kg. The bottom of the ladder is at the point of slipping, outward from the wall, just as the person reaches the mid-point of the ladder’s length. Draw a free body diagram of the ladder and calculate the maximum frictional force opposing the slipping motion. In addition, determine the angle of inclination (θ) of the ladder, when the person is at the mid-point and the ladder is on the verge of slipping.
Shown in the figure below is a magazine resting on top of a book. There is static friction between the magazine and the book and there is kinetic friction between the book and the table. If you pull very gently on the book, both objects slide together. If you pull very forcefully, you will slide the book out from under the magazine. In this problem, we will determine the MAXIMUM FORCE that you can apply and still have the magazine come along for the ride.

A body of weight 500N is prevented from sliding down a plane inclined at 20 to the horizontal by the application of a force of 50 N acting upwards and parallel to the plane. Find the coefficient of friction. If the body is to be pulled up the plane by a force acting at an angle of 30 to the horizontal, find the value of the force, and the efficiency of the lift. IMECHE
