A force distribution system consisting of four rods in
series connection are supported by two fixed
supports, one at each end. Each rod experiences
both thermal expansion and an external axial force
applied at the junctions between the rods. During an
operation, consider the following: • The rods are subjected to a temperature rise of 50 K. • At the junction between the first two rods, there is an
external concentrated force of 50 kN, and 100 kN at the
junction between the next two rods.
Length (m): 2,3,4,1
Cross-section (m2): .01, .015, .02, .01
Modulus of Elasticity (GPa): 200, 70, 200, 70
Coefficient of Thermal Expansion (per K): 12 x 10^-6, 23 x 10^-6, 12 x 10^-6, 23 x 10^-6
