A hungry bear weighing \(700\,\text{N}\) walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam. The beam is uniform, weighs \(200\,\text{N}\), and is \(6.00\,\text{m}\) long. The goodies weigh \(80\,\text{N}\).(a) Draw a free-body diagram for the beam when the bear is at \(x = 1.0\,\text{m}\). , (b) Find the tension in the wire supporting the beam. , (c) Find the components of the reaction force at the hinge. :

a) The tension in the cable is: [katex]T = 342.56\text{N}[/katex] b) The vertical reaction force is: [katex]R_v = 683.33\text{N}[/katex] c) The horizontal reaction force is: [katex]R_h = 171.28\text{N}[/katex]
