A 2 m copper bar subjected to a tensile load 180 kN is suspended from a pin that is supported by two identical steel posts as shown. Determine the total deformation of the lower end of the copper bar due to the applied tensile load. HINT: Note that the steel posts support the pin where he copper bar is attached. Use 3 decimal places in every solved value. steel post L = 0.5 m A = 4500 mm? E = 200 GPa соррer bar L = 2 m A = 4800 mm² E = 120 GPa

Dimensional homogeneity

The term dimensional homogeneity means that in an equation, the dimensions of each term on both sides are equal, which means the dimensions of the left-hand side (LHS) of an equation are similar to the dimensions of the right-hand side (RHS). For a dimensionally homogeneous equation, the powers of fundamental dimensions will be identical on both sides of the equation.
