Exercise : Theory of Structures - Section 2
1.
By applying the static equations i.e. ΣH = 0, ΣV = 0 and ΣM = 0, to a determinate structure, we may determine
supporting reactions only
shear forces only
bending moments only
internal forces only
all the above.

No answer description is available. Let's discuss.

2.
The general expression for the B.M. of a beam of length l is the beam carries a uniformly distributed load w/unit length
a load varying linearly from zero at one end to w at the other end
an isolated load at mid span
none of these.

3.
The ratio of the length and diameter of a simply supported uniform circular beam which experiences maximum bending stress equal to tensile stress due to same load at its mid span, is    1.0

4.
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
