A 45.0-kg child swings in a swing supported by two chains, each 3.06 m long. The tension in each chain at the lowest point is 346 N.

A hungry bear weighing 730 N walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam (see the figure below). The beam is uniform, weighs 200 5.00 m long, and it is supported by a wire at an angle of 0 = 60.0°. The basket weighs 80.0 N. Goodies Q (a) Draw a force diagram for the beam. (Submit a file with a maximum size of 1 MB.) Choose File No file chosen This answer has not been graded yet. (b) When the bear is at x = 1.16 m, find the tension in the wire supporting the beam. N When the bear is at x = 1.16 m, find the components of the force exerted by the wall on the left end of the beam. (Assume the positive +x direction is to the right and the positiv direction is upward. Include the sign of the value in your answer.) Fx N N (c) If the wire can withstand a maximum tension of 775 N, what is the maximum distance the bear can walk before the wire breaks? m

Two identical, side-by-side springs with spring constant 240 N/m support a 2.00 kg hanging box. Each spring supports the same weight. By how much is each spring stretched?

How do you do this? A hungry bear weighing 700 N walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam (see figure below). The beam is uniform, weighs 200 N, and is 6.00 m long, and it is supported by a wire at an angle of ? = 60.0°. The basket weighs 80.0 N. a) When the bear is at x = 1.00 m, find the tension (in N) in the wire supporting the beam and the components of the force exerted by the wall on the left end of the beam. b) If the wire can withstand a maximum tension of 875 N, what is the maximum distance (in m) the bear can walk before the wire breaks?
