For the following questions answer them individually
A compound bar consists of two bars of equal length. Steel bar cross-section is 3500 $$mm^{2}$$ and that of brass bar is 3000 $$mm^{2}$$. These are subjected to a compressive load 100,000 N. If $$E_b=0.2$$ $$\frac{MN}{mm^{2}}$$, the stresses developed are
The radius of gyration of rectangular section (depth D, width B) from a centroidal
axis parallel to the width is
For determining the force in AB of the truss shown in the figure below by method of sections, the section is made to pass through AB, AD and ED and the moments are taken about
