Question

3 (a). A brass wire is 380 mm in length and 12.5 mm in diameter. Under tensile loading,it is noticed that plastic deformation starts when the load reaches 7063 lbs. What isthe yield stress of the brass? (in both MPa and P)(b).When loaded to 3356 kg the total (elastic + plastic) strain was 0.013 mm/mm. Thewire was then unloaded. What is the length of the wire after unloading (in mm)?Assume Elastic modulus of this brass is 110000 MPa. Assume engineering stressand strain.Would your results change if you had assumed true strain in your solution? If so,how?(c).
