For the stepped cantilever beam shown, using deterministic Finite Element Analysis, obtain the vertical displacement at the free end, as well as the first $($fundamental$)$ natural circular frequency.

Structural Notes:

The stepped Cantilever Beam is made of cross laminated timber $($CLT$)$

The species of wood is Douglas Fir: $E=1,720,000$

The shallowest section has an area of $A=16i{n}^2$

The shallowest section has a moment of inertia $I=85$ in ${?}^4$
