Theory of Structures parabolic arch of span and rise , is given by The equation of a y = 3h/l² × (1 – x) y = 2h/l² × (1 – x) y = 4h/l² × (1 – x) y = h/l² × (1 – x ) y = 3h/l² × (1 – x) y = 2h/l² × (1 – x) y = 4h/l² × (1 – x) y = h/l² × (1 – x ) ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A simply supported uniform rectangular bar breadth b, depth d and length L carries an isolated load W at its mid-span. The same bar experiences an extension e under same tensile load. The ratio of the maximum deflection to the elongation, is (L/3d)² L/2d L/d (L/2d)² (L/3d)² L/2d L/d (L/2d)² ANSWER DOWNLOAD EXAMIANS APP
