For the cross section shown below, the material and sectional properties are given as follow

$f_c^{\text{'}}=4$ksi,$f_y=60$ksi,$b=30in,d=20in,$ concrete cover depth $1\mathrm{.}5in.E_s$:$=29000000*$ psi, Four No$.8$ bars used for reinforcement.

Tensile strength of concrete is $500$ psi.

Determine the modular ratio. The concrete modulus of elasticity can be estimated by $5700f_c^{\text{'}}[]$ where $f_c^{\text{'}}$ must be in unit psi.
