The adjacent sketch indicates a brass wire which is exactly 12.00 m long and a steel wire which is 12.01 m long. Each wire has a cross-sectional area of 150 mm2 . What load does each wire carry if E steel = 200,000 MPa & E brass = 110,000 MPa? (Hint: no load on steel wire until brass wire stretches by 10mm, then ratio of stresses in each wire is same as ratio of E v
