The horizontal uniform rod shown below has length 0.60 m and mass 2.0 kg. The left end of the rod is attached to a vertical support by a frictionless hinge that allows the rod to swing up or down. The right end of the rod is supported by a cord that makes an angle of 30° with the rod. A spring scale of negligible mass measures the tension in the cord. A 0.50 kg block is also attached to the right end of the rod.

A hungry bear weighing 85.0 kg walks out on a beam in an attempt to retrieve a basket of food hanging at the end of the beam. The beam is uniform, has a mass of 20.0 kg, is 8.00 m long, and pivoted at the wall; the basket weighs 10.0 kg. If the wire can withstand a maximum tension of 900 N, what is the maximum distance that the bear can walk before the wire breaks? ←x 60.0⁰ Goodies
A 24 kg rectangular 4.00 m x 3.00 m rectangular sign is suspended from a horizontal 6.00 m long rod with a 5 kg mass as indicated in the figure. 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. Draw a free body diagram and calculate the tension T in the cable. The thin cable breaks if it is pulled by more than 200 N. Show than in the present situation the cable can not support the sign without breaking. Show the cable is able to support the load if it is attached higher up such that it makes an angle of 20.0° angle S0.0 CE CREAM SHOP with the vertical.

It's exciting watching the construction and renovation happening in Uptown Columbus! On one construction site, you notice that a uniform beam of length 13.6 m and mass 47.9 kg is attached to a wall by a cable. The angle between the cable and the beam is 59.5°. The beam is free to pivot about the point where it attaches to the wall. What is the tension in the cable, if the beam is not moving? Your Answer: Answer
As shown below, a beam of length L is in equilibrium and is attached to a cable which is pulling it against a frictionless wall. The beam is not attached to the wall and the wall is only exerting a normal force on the beam. Additionally, there is a 702 N box hanging on a wire from the end of the beam. Determine the cable tension & the beam weight. 0.89 L 45° tension = beam weight = 702 N
