QUESTION $6$

The tangents for a $\backslash (\backslash$mathrm$\{$D$\}=4^\{\backslash$circ$\}30^\{\backslash$prime$\}\backslash )$ highway horizontal curve meet at PI Sta $35+18\mathrm{.}19$ and the deflection angle $\backslash (\backslash$mathrm$\{$I$\}=25^\{\backslash$circ$\}48^\{\backslash$prime$\}\backslash ).$

$1)$ Compute L$,$ T$,$ E$,$ M$,$ LC$,$ R for circular curves $(10\text{'}).$

$2)$ Calculate the Stations of the PC and PT$,$ plus the total chords and deflection angles for all the full stations on the curve $(15\text{'}).$

$3)$ A $200$ ft spiral curve transition the tangent line into the above horizontal curve. Stake out the spiral curve at $50$ ft stations by computing the deflection angles and chords $(15\text{'}).$ Attach File
