Question

A hungry bear weighing 735 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 N, and is 6.50 m long, and it is supported by a wire at an angle of ? = 60.0°. The basket weighs 80.0 N.

(a) Draw a force diagram for the beam. (Submit a file with a maximum size of 1 MB.)

This answer has not been graded yet.

(b) When the bear is at x = 1.14 m, find the tension in the wire supporting the beam.
________________________N

When the bear is at x = 1.14 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 positive +y direction is upward. Include the sign of the value in your answer.)

Fx ___________

Fy ___________

(c) If the wire can withstand a maximum tension of 825 N, what is the maximum distance the bear can walk before the wire breaks?
