1.For a given two-dimensional (x,y) Free body diagram (FBD) that is in Static Equilibrium, what are the two equations that civil engineers balance and use to solve for the forces?
2.Write out the final version of Hooke's Law which includes Young's Modulus. Draw the idealized Stress-Strain diagram for a material. On the drawing, please label: the yield stress, the plastic deformation, and the yield strain.
