A three hinged parabolic arch is subjected to a udl of 80 kN/m on the left half of the
span. It has a span of 16 m and central rise of 3 m. The horizontal thrust at the left
support will be :

(^) 80kN (B) 120 kN

If a deformable structure in equilibrium under the action of a system of loads is given
a small virtual deformation, then the virtual work done by the external forces is
equal to the virtual work done by the internal forces. This prineiple is known as :

(A) Principle of virtual displacements

(B) Principle of virtual work

(C) Principle of complimentary work

(D) Principle of complimentary displacements
