A 560-N uniform rectangular sign 4.00 m wide and 3.00 m high is suspended from a horizontal, 6.00-m-long, uniform, 120-N rod as indicated in the figure below. The left end of the rod is supported by a hinge and the right end is supported by a thin cable making a 30.0° angle with the vertical. (Assume the cable is connected to the very end of the 6.00-m-long rod, and that there are 2.00 m separating the wall from the sign.)...

In the figure, a uniform beam of weight 470 N and length 3.6 m is suspended horizontally. On the left it is hinged to a wall; on the right it is supported by a cable bolted to the wall at distance D above the beam. The least tension that will snap the cable is 1400 N. What value of D corresponds to that tension?

A uniform door (0.79 m wide and 2.0 m high) weighs 113 N and is hung on two hinges that fasten the long left side of the door to a vertical wall. The hinges are 2.0 m a part. Assume that the lower hinge bears all the weight of the door. Find the horizontal component of the forces, including sign, applied to the door by (a) the upper hinge and (b) the lower hinge, taking the direction to the right...

A 3 meter uniform rod with a weight of 1000 N is suspended by two vertical cables and has a large box (1750 N in weight) tied to the right hand side. One cable is exactly on the left most end of rod with a tension of 2000 N. The second cable is 1 m to the right of the center of mass and has an unknown tension. What angle does the rod make with the force of the hanging...

A farm gate (Fig. P12.44) is 3.00 m wide and 1.80 m high, with hinges attached to the top and bottom. The guy wire makes an angle of 30.0° with the top of the gate and is tightened by a turnbuckle to a tension of 200 N. The mass of the gate is 40.0 kg. (Assume that the positive directions are upward and to the right.) Find the horizontal force exerted by the upper hinge. What if? What must be...

A 1,300–N uniform boom at ϕ = 60.0° to the horizontal is supported by a cable at an angle θ = 30.0° to the horizontal as shown in the figure below. The boom is pivoted at the bottom, and an object of weight w = 1,950 N hangs from its top. A boom of length l with its bottom end on a pivot is shown. The boom points up and to the right and makes an angle ϕ with the...

1. A uniform bar of length 4.7 m and mass 4.4 kg is attached to a wall through a hinge mechanism which allows it to rotate freely. The other end of the bar is supported by a rope of length 5.6 m which is also connected to the wall. What is the tension in the rope in N? 2. A uniform bar of length 5 m and mass 4.2 kg is attached to a wall through a hinge mechanism which...

A uniform 1.8-kg rod that is 0.88 m long is suspended at rest from the ceiling by two springs, one at each end. Both springs hang straight down from the ceiling. The springs have identical lengths when they are unstretched. Their spring constants are 36 N/m and 52 N/m. Find the angle that the rod makes with the horizontal.

A uniform, 245-N rod that is 2.10 m long carries a 225-N weight at its right end and an unknown weight W toward the left end (see the figure (Figure 1)). When W is placed 46.0 cm from the left end of the rod, the system just balances horizontally when the fulcrum is located 69.2 cm from the right end. W= 71.7 N If W is now moved 28.1 cm to the right, how far must the fulcrum be moved...
