A hungry 800-N bear walks out on a beam in an attempt to retrievesome "goodies" hanging at the end. The beam is uniform, weighs 200N, and is 6.00 m long; the goodies weigh 90.0 N.
(a) Draw a free-body diagram of the beam. (Do this on paper. Yourinstructor may ask you to turn in this sketch.)
(b) When the bear is at x = 1.00 m, find the tension in the wireand 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 1020 N, what isthe maximum distance the bear can walk before the wirebreaks?
____ m
