If the normal stresses due to longitudinal and transverse loads on a bar are $$\sigma_1$$ and $$\sigma_2$$ respectively, the tangential component of the stress on an inclined plane through $$\theta^\circ$$, the longitudinal load is

The moment of inertia of a triangular section (height h, base b) about its base is

In the truss shown below, the force in the member AC is

The force in BC of the truss shown in the figure below is

If a solid shaft (diameter 20 cm, length 400 cm, N = 0.8 x 105 N/mm2) when subjected to a twisting moment, produces maximum shear stress of 50 N/mm2, the angle of twist in radians is

The load on a spring per unit deflection is called

In case of a simply supported rectangular beam of span L and loaded with a central load W, the length of elasto-plastic zone of the plastic hinge is

There are two hinged semicircular arches A,B and C of radii 5 m, 7.5 m, and 10 m respectively and each carries a concentrated load W at their crowns. The horizontal thrust at their supports will be in the ratio of

For determining the support reactions at A and B of a three-hinged arch, points B and C are joined and produced to intersect the load line at D and a line parallel to the load line through A at D'. Distances AD,DD' and AD' when measured were 4 cm, 3 cm and 5 cm respectively. The angle between the reactions at A and B is

The equivalent length of a column of length L having one end fixed at the other end free is
