60.0°
Goodies
(a) Draw a free-body diagram of the beam. (Do this on paper. Your instructor may ask you to turn in this sketch.)
(b) When the bear is at x = 1.00 m, find the tension in the wire and the components of the reaction force at the hinge.
N (tension)
N (horizontal reaction)
N (vertical reaction)
(c) If the wire can withstand a maximum tension of 870 N, what is the maximum distance the bear can walk before the wire breaks?
