A composite square member of varying sizes is subjected to axial forces along its centerline, as shown. The members' cross-sectional dimensions, from smaller to larger, are 50 mm ´ 50 mm, 75 mm ´ 75 mm, and 100 mm ´ 100 mm, respectively. (a) What are the normal stresses (in MPa) induced in the bar material at Section A-A, Section B-B, Section C-C? (b) What are the changes in the axial (4.28 ft), width (100mm), and thickness (100 mm) direction (in mm), at Section C-C? Assume n = 0.25 and E = 200,000 MPa., 1 ft = 0.3048 m

Question
A composite square member of varying sizes is subjected to axial forces along its centerline, as shown. The members' cross-sectional dimensions, from smaller to larger, are 50 mm ´ 50 mm, 75 mm ´ 75 mm, and 100 mm ´ 100 mm, respectively.
(a) What are the normal stresses (in MPa) induced in the bar material at Section A-A, Section B-B, Section C-C?
(b) What are the changes in the axial (4.28 ft), width (100mm), and thickness (100 mm) direction (in mm), at Section C-C?
Assume n = 0.25 and E = 200,000 MPa., 1 ft = 0.3048 m
