Question

A 60mm tall by 16mm wide by 2mm thick into the paper) rectangular test specimen carries an axial load of 1200N. The axially oriented instrumentation measures an elongation of 0.014mm over a gage length of 26mm. The transversely oriented instrumentation measures a contraction of 0.0018mm over a gage length of 10mm. The loading remains in the linearly elastic range. 16 mm 26 mm 60mm 10 mm The transverse strain in the specimen is most nearly -1.1 x 10-4 -1.8 x 10-4

Answer 1

transversely Given that, contrachion, Alt +0.0018 gauge length, L=10mm. transverse strain, Et= -sd d. € 0.0018 lo mm G =-0.00018 mm mm &=-1.8x10t transvers se strain
