The windshield of an automobile is manufactured by sandwiching a 0.02 cm thick sheet of polymer (E = 4.8 GPa) between two 4.5 mm thick glass sheets (E = 82.7 GPa). Calculate the modulus of elasticity of the windshield parallel and perpendicular to the sheet.
Added by Mark K.
Step 1
To calculate the modulus of elasticity parallel to the sheet, we need to consider the composite structure of the windshield. The glass sheets are much thicker than the polymer sheet, so we can assume that the glass sheets contribute most to the overall stiffness Show more…

A steel bar 100 mm long and having a square cross section 20 mm on an edge is pulled in tension with a load of 97,384 N , and experiences an elongation of 0.11 mm . Assuming that the deformation is entirely elastic, calculate the elastic modulus of this steel in GPa. (answer format X, no decimal places)
