Unformatted text preview: Emch213 HW quiz 2 solution 1. The rigid bar ABCD is supported by two rods as shown. There is no strain in the vertical rods before load P is applied. After load P is applied, the normal strain in rod (1) is -1000 x 10—6 mm/mm. Determine the normal strain in rod (2). The dimensions of the system are L1 = 650 mm, L2 = 650 mm, AB = 240 mm, BC = 360 mm, and CD = 140 mm. , Solution: Lo) '3) ALO): LU) ' in) : (€390 m")(”"w/"Bc mm [in/fl '3 '09; mm (Compt/YSSW“). i <5 ‘3 N U7 3 3 ll .
