Exercise 16

Figure RT 5.5 shows a roof truss

\mathrm { PQR }

with rafter

\mathrm { PQ } = 3 \mathrm {~m}

Calculate the length of (a) the roof rise

\mathrm { PP } ^ { \prime }

, (b) rafter

\mathrm { PR }

, and (c) the roof span

\mathrm { QR }

.
Find also (d) the cross-sectional area of the roof truss.
