For this example, the width of the house is 20 feet at the top plate and 30 feet long.13 SOLUTION Externally stable, since the reactions are not concurrent or parallel.Since b = 19, r = 3, j = 11, then b + r = 2j or 22 = 22. Therefore, the truss is statically determinate. By inspection the truss is internally stable. Externally stable.Since b = 15, r = 4, j = 9, then b + r > 2j or 19 > 18. The truss is statically indeterminate to the first degree.By inspection the truss is ...Suppose the base of the actual roof is measured to be 40 feet. You can set up the following equivalence: base of triangle/base of actual roof = hypotenuse of triangle/hypotenuse of roof. Plugging in the numbers, you get 1/40 = 1.06 /x, where x is the required rafter length. Solving for x, you get x = (40) ( 1.06) = 42.4 feet.
