$1)$ A $10-$ft long rigid structure is modeled as the

cantilevered bar AB in the figure. The lift of the

wing is modeled as w$($x$)=3*$sqrt$($x$)$ lb$/$ft$,$ with x $=0$

at the left end $($A$).$ Ignoring the weight of the

structure:

a$)$ Draw the free$-$body$-$diagram

b$)$ Calculate the reactions at the wall using

integration only.

c$)$ Calculate the centroid of the load w$($x$)$ and use

it to check part b by solving for the reactions

using the equivalent point force.
