Select the correct options, given that the beam on the right is a sawn lumber beam made of Douglas$-$Fir $4"$x No$1$ & Btr grade.

w$=195$ pounds per linear feet $($lbs$/$ft$)$

The maximum deflection in the beam is $0\mathrm{.}575$ in

The minimum section modulus required is $135\mathrm{.}66i{n}^3$

The minimum section modulus required is $97\mathrm{.}5i{n}^3$

The maximum deflection in the beam is $0\mathrm{.}329$ in

Sawn lumber section with nominal size $($bxd$)414$ will be safe under bending

The maximum deflection in the beam is $0\mathrm{.}769$ in
