Problem $1$: $(10$ pts$)$ The truss shown below is subjected to $F_1=4kN,F_2=6kN.|AB|=|BC|=|CD|=1m,|GE|=|EF|=1m.$ Assume support at $A$ is a pin connection while support at $F$ is a roller that allows vertical movement.

Determine the support reactions at A and $F.$

Find the internal forces in $AB,BG$ and $GD.$
