A truss consists of ten members joined by seven pins. The pin at $\text{'}$A$\text{'}$ is fixed to a horizontal surface. The free pin at B is $1$ meter to the right of $\text{'}$A$\text{'}.$ The free pin at C is $2$ meters to the right of B$.$ The free pin at D is $1$ meter to the right of C$.$ The free pin at E is $2$ meters above C$.$ The free pin at F is $2$ meters above B$.$ The pin at G is fixed to a vertical surface $2$ meters above $\text{'}$A$\text{'}.$ The members are $\text{'}$A$\text{'}$ B$,$ B C$,$ C D$,$ D E$,$ E F$,$ G F$,\text{'}$A$\text{'}$ F$,$ B F$,$ B E$,$ and C E$.\text{'}$A$\text{'}$ B$,$ B C$,$ C D$,$ E F$,$ and G F are horizontal. B F and C E are vertical. Load P subscript $1$ is applied at B and is directed vertically downward. Load P subscript $2$ is applied at D and is directed vertically downward.
