Given that $lc\frac{r}{l}g=0\mathrm{.}35$ and $Mc\frac{r}{?}Ma=0\mathrm{.}55$ for a beam of $300mm$ and $600mm$ depth. What is the ratio of le$/$lg$?$

Select one:

a$.0\mathrm{.}458$

b$.0\mathrm{.}431$

c$.0\mathrm{.}3916$

d$.0\mathrm{.}35$

The deflection increases as:

Select one:

a$.$ the span length decreases

b$.$ the moment of inertia decreases

c$.$ the moment of inertia increases and span length decreases

d$.$ None of the above.

The moments result from lateral deflections of the beam $-$ column joints from their original undeflected locations is called:

Select one:

a$.P-$ moments

b$.$ P$-$ moments

c$.$ nonsway moments.

d$.$ beam moments
