A compound bar, 1.5m long is made up of three concentric square components A, B and C, fitted tightly together as shown in Fig.1. Each component is of a different material and the properties are as follows: EA200 GN/m², EB- 120 GN/m², Ec- 80 GN/m² Assuming all the 3 materials are ductile. a) Calculate the stress in each component when the tensile force W = 500 KN. b) Calculate the extension of the bar under this force. c) What is the maximum Force that can be applied to the bar before failure occurs? Knowing that maximum stresses are GA-250 MN/m², OB-160 MN/m², and oc=116 MN/m² B A 2612272 (1) 16 00 00 728212 50 mm 75 mm 100 mm Fig 1 Cross Section of the Compound Bar 10 3. 2 16.7
