Q$6)$

As shown, a truss is loaded with forces $P1=0\mathrm{.}895kN$ and $P2=1\mathrm{.}81kN$ and has the dimension $a=1\mathrm{.}40m.$

a$)$ Using the method of joints, determine $F_{AB},F_{BC},$ and $F{B}_B,$ the magnitude of the force in each of the members connected to joint $B.$

b$)$ Identify whether each member of the truss is in tension or compression. Although the sense of most members was determined in Part B$,$ the method of joints must still be applied.
