Question

Linear systems occur in the design of roof
trusses for new homes and buildings. The simplest type of roof
truss is a triangle. The truss shown in the figure below is used
to frame roofs of small buildings. If a 100-lb force is applied
at the peak of the truss, then the forces or weights W1 and W2
exerted parallel to each rafter of the truss are determined by the
following linear system of equations.

(W, + W2) = 100
W, - W, = 0
Solve the system to find W and W,. Source: Structural Analysis.
