SITUATION $06-$ A rectangular reinforced concrete beam has a width of $250$ mm and a total depth of $600$ mm $,$ and an effective depth of $500$ mm $.$ It is reinforced with $3-D25.f{c}^{\text{'}}=28$MPa. fy $=415$MPa. The beam is carrying a slab $150$ mm thick, $5$ m wide. The beam has a span of $6$ m $.$ If the unit weight of concrete is $24k\frac{N}{m^3},$

$15.$ What is the unfactored dead load acting on the beam?

a$.21\mathrm{.}6K\frac{N}{m}$

b$.18K\frac{N}{m}$

c$.25K\frac{N}{m}$

d$.24K\frac{N}{m}$

$16.$ What is the ultimate moment capacity?

a$.222KN-m$

b$.247KN-m$

c$.196KN-m$

d$.274KN-m$

$17.$ What is the unfactored live load that the beam would support?

a$.21\mathrm{.}6K\frac{N}{m}$

b$.14\mathrm{.}63K\frac{N}{m}c\mathrm{.}23\mathrm{.}4K\frac{N}{m}$

d$.18\mathrm{.}07K\frac{N}{m}$
