GP

The assembly consists of two red brass C83400 copper rods AB and CD having a diameter of30 mm, a 304 stainless steel rod EF having a diameter of 40 mm, and a rigid member G. The supports at A, C and F each have a stiffness of k = 200 MN/m . The modulus of elasticity for red brass C83400 is 101 GPa and for 304 stainless steel is193 GPa.

Determine the average normal stress developed in the rods AB and CD when the load is applied.


Determine the average normal stress developed in the rod EF when the load is applied

The trouble I'm having is where the stiffness k comes into play...
