$1-$Using the Ashby Diagram below, please name the metal that has the highest

range of density. Additionally, name any $3$ other non$-$metals that have the same

or similar strengths as that material. Explain your reasoning.

$2.$ A$.$ Given a steel beam with a Modulus of Elasticity of $200$ GPa and a density of

$7\mathrm{.}85$g$/$cm$^3,$ find the ultimate strength. Remember that your Young$$s Modulus is in

GPa, or Gigapascals, denoted by $1$ X $109$ N$/$m$2$

$.$

B$.$ What if instead the beam was annealed cartridge brass? Use a Modulus of

$110$ GPa and the attached pdf from the textbook of strengths and find the density.
