Problem $1.$

Continue on example $1$ and $2$ on on June $06$ th slides. Given the internal force coefficient of ab$,$ de$,$ bc$,$ and cd$,$ please complete the table below.

Hint: dead load $P1=7\mathrm{.}1kN$ and live load $P2=5\mathrm{.}05kN,$ and the internal force under each load can be solved by

Internal force under dead load: $F=P1**C1$

Internal force under live load $($whole roof$)$: $F=P1**C1$

Internal force under live load $($half roof$)$: $F=P1**C2$
