Q A simple horizontal circular curve has: $=4524,D=0630$ station P$.$I $=(40+20)$ Calculate:

$1-$ the all elements and stations

$2-$ coor dinates of station $($P$.$I,P$.$T$),$ if azimuth of P$.$T $P*C={28007}^{\text{'}}$ and Coordinate of $P.C=(250,250)$

$(1)R$

$(2)$ T

$(3)C$

$(5)$ E

$(6)M$

$D=\frac{573}{R}$

$T=$Rtan$(\frac{}{2})$

$=2$Rsin$(\frac{}{2})$

$L=\frac{R}{180}$

$E=R(\frac{1}{cos(\frac{}{2})}-1)$

$M=R(1-cos(\frac{}{2}))$

sta.$P.C=5t\frac{a}{P}$I $-T$

Sta $P.T=3$taP$*C+L$
