The figure shows a 4.20-kg, 1.80-m-long rod hinged to a vertical wall and supported by a thin wire. The wire and rod each make angles of 45° with the vertical. When a 10.0-kg block is suspended from the midpoint of the rod, the tension T in the supporting wire is 49.3 N. The wire will break when the tension exceeds 75.0 N. 45° 45° T 10kg Tipler & Mosca, Physics for Scientists and Engineers, 6e © 2008 W.H. Freeman and Company What is the maximum distance dmax from the hinge from which the block can be suspended? dmax = m

A uniform 8.00 m, 1500 kg beam is hinged to a wall and supported by a thin cable attached 2.00 m from the free end of the beam. The beam is fixed to the wall at an angle of 30 degrees above the horizontal. The angle between the cable and the beam is 40 degrees. What are the unknowns? -direction of tension in the cable -direction of the hinge force -magnitude of rhe tension in the cable -magnitude of the hinge force

A 25-ft crane supported at its lower end by a pin is elevated by a horizontal cable. A 250-lb load is suspended through the cable. The center of gravity of the crane is 10 ft from the pin, and the crane weighs 200 lb. Hint: You don't have to convert the unit since they cancel out on both sides. 25. Find the tension in the cable. T $25016 26. Find the total force acting on the pin. y 27. Find the direction of the force acting on the pin, o = ? 60⁰° W(2001b)

A force stretches a wire by 4.0 mm. A second wire of the same material has the same cross section and twice the length. How far will it be stretched by the same force?     4.0 mm     1.0 mm     2.0 mm     8.0 mm     16 mm

H 60° Figure 6 G M 8. A uniform rod HG of length 2L m and mass m = 2 kg is hinged at end H, as shown in Figure 6 A mass Mg=100 N is hung at the other end G. A horizontal cable at the midpoint of the rod holds it at an angle of 60° to the horizontal. The cable is under a constant tension T. (a) Draw a diagram showing all the forces acting on the rod and determine the tension T in the cable. (b) Calculate both the x and y components (Fr and F₁) of the force F at the hinge H. (c) Will the net force F at H act along the rod HG? Justify your answer.

A 45.1 kg man is walking on a 147 kg uniform beam that is attached 19.0 m below the top of a building and is 21.2 m long.  If a wire is attached to both the top of the building and end of the beam, and is able to handle 1.52E3 N of tension, how close to the end can the man walk before the wire breaks?

1. A 80.0-N board 10.0 m long rests on two supports, each 1.00 m from the end of the board. A 300-N block is placed on the board 4.00 m from the right end. Find the force exerted by each support on the board.
