A rigid horizontal bar is supported by two axial bars with circular cross$-$sections with diameters $d$

at the left and right ends as shown. The bars are of equal length $(0\mathrm{.}5$ meters$)$ and have these

properties: Bar $(1)-d_1=15mm,E_1=140$GPa. Bar $(2)-$ Bar $2-d_2=10mm,E_2=200$GPa. Find the

downward deflection at the left and right ends $B$ and $C$ of the horizontal bar and the angle that

the final displaced rigid bar makes with the horizontal. Hint: Remember for statics, to get $1$

equation and $1$ unknown for problems like this, take moments about either end first to get one

reaction$/$bar force, then sum forces vertically to get the second. Answers: ${}_B=0\mathrm{.}269mm$

downward, ${}_c=0\mathrm{.}212mm$ downward, the bar is $0\mathrm{.}00435$ degrees ccw from the horizontal.
