- A sign is hung from the wall of a building using an angled beam and a support cable. The beam(mass = 1500kg, length = 8m) is bolted to the wall and angled up at 30◦above the horizontal. Themass-less support cable is attached to the beam 2m from its far end and makes an angle of 40◦betweenthe beam and the cable.

Calculate the force in the Achilles tendon if he stands on one foot and has a mass of 80kg.A sphere of mass 3.5 kg is attached to one end of a rope. The work done to pull the sphere up 1.5 m is 550 J. What is the tension in the rope?A 2.4 m ladder rests on a vertical wall as shown in the figure. The ladder has 7 rungs and the rungs are spaced 0.30 m apart, and the top and bottom rungs are 0.30 m from their respective ends of the ladder. Surfaces at A and B both have the same coefficient of friction. If a worker weighs 360 N and stands on the middle rung, determine the minimum value of the coefficient of friction so that the ladder does not slide. Neglect the weight of the ladder.

If the fulcrum is located at the center of the board, where should a 40kg cat hang in order to balance the beamA cable with length 17m has a mass of 34kg and is hanging off of the side of a building. Acceleration due to gravity is g = 9.8 m/s^2. Find the work done in winding up the cable. Round your answer to the nearest tenth if necessary.A beam is connected to the floor by a hinge. A rope is attached to the other end of the beam. The other end of the rope is connected to the ceiling. There is box sitting on the beam (see figure).The angle between the beam and the floor is 8.80 degrees. The angle between the rope and the horizontal is 25.0 degrees. The beam is 3.70-m long and has a mass of 4.40 kg. The box sits a distance of d = 0.890 m from the upper end of the beam and has a mass of 8.50 kg. The tension in the rope is 150.7 N.What is the vertical component of the force on the beam due to the hinge?
