1. The picture shows a gibbon hanging from a tree branch in tropical forest. If you know the mass of the gibbon and the angles made by the hands either with horizontal or vertical direction, you should be able to calculate force or tension on each hand of the gibbon using equilibrium conditions after drawing a free body +y diagram. The sketch shows a free body diagram of the gibbon. T1 T2 a. (10 points) Draw the components of forces T1 and T2 along the x and y axes and list the values (ignore signs as 02 +x your sketches will show the direction of components) in terms of T1, q1 and T2, q2 below mg T1x = Tıy = %3D %3D T2x = Tzy = b. (10 points) Use equilibrium conditions along x and y directions. It will result into two equations. c. (10 points) Assuming m = 55 kg, 01 = 65 degrees and 02 = 35 degrees solve above equations for T1 and %3D %3D T2.
