Calculate the deflection at point C of a beanm subjected to uniformly distributed load w 275 N/mm on span AB and point load P-10
lakkis [162]

Answer:

Deflection at point C = 0.151 m

Explanation:

Central deflection due to uniformly distributed load w for simply supported beam

         \delta =\frac{5wl^4}{384EI}

Central deflection due to point load P for simply supported beam

         \delta =\frac{Pl^3}{48EI}

Here deflection

          \delta =\frac{5wl^4}{384EI}+\frac{Pl^3}{48EI}=\frac{5\times 275\times 10^3\times 5^4}{384\times 1.5\times 10^7}+\frac{10\times 10^3\times 5^3}{48\times 1.5\times 10^7}\\\\\delta =0.149 + 1.74\times 10^{-3}=0.151m

Deflection at point C = 0.151 m

<h3>A skin infection: how do you treat it?</h3>

Depending on the infection's origin and intensity, different treatments are available. It may take days or weeks for some viral skin infections to heal on their own. Antibiotics taken orally or administered topically to the skin are frequently used to treat bacterial infections.

What Occurs at divergent boundaries and creates new seafloor
lisabon 2012 [21]
Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.
