A two-member truss is subjected to a load P = 8000 N. Member 1â€“2 is 400 mm long. Member 1â€“3 was manufactured to be 505 mm long instead of 500 mm. However, it was forced into place. Determine (a) the stresses in the members assuming that member 1â€“3 was manufactured to its correct length of 500 mm (b) the stresses in the members as a result of member 1â€“3 being forced into place (and the load P , of course). ( Hint : Treat this as an initial strain problem and use the temperature load vector expression in the text.) Take cross-sectional areas = 750 mm 2 , E = 200 GPa.
