Problem 5.11 (Multistep) A load of 860 kg is suspended as shown in the figure. The angle 01 =72º and the angle 02 =20°. Part 1 Your answer is partially correct. Try again. (a) Calculate the tension in all three wires (that is, the magnitude of the tension force exerted by each of these wires). Tension in left wire = 8015.5 Tension in right wire = 2884 Tension in bottom wire = 8428

Part 2 Your answer is partially correct. Try again. (b) These wires are made of a material whose value for Young's modulus is 1.4 x 1011 N/m2. The diameter of the wires is 1.3 mm. What is the strain (fractional stretch) in each wire? Strain in left wire = 4.31565e-2 1.5533e-2 Strain in right wire = Strain in bottom wire = 14.5377e-2
