Problem 1.1 Find the equivalent stiffness at point A. Answer: 9.20106 N/m Problem 1.2 Consider a stainless-steel metal ruler. Assume it is 12 in long, 1.25 in wide, and 0.018 in thick with an elastic modulus of 2810 psi. a) Find the equivalent stiffness for each of the three directions. b) Do your results make sense? Why or why not? Answer: a) kx=52,500 lb/in, ky 142 lb/in, kz=0.0295 lb/in z (up and down) x (side to side) y (front to back) 0.2 m 0.4 m m A Massless Beam Length L = 0.6 m Thickness t = 0.01 m Depth d=0.3 m Modulus E 200 GPa =
