For a parabolic three hinged arch subjected to a uniformly distributed load of
intensity ‘w’ kN per unit horizontal length. The span of the arch is ‘L’ units and the
central rise ‘h/2 units. The horizontal thrust (H) of the arch is :

When a uniformly distributed load shorter than the span is traversing a simply
supported beam. At any point in the beam, maximum value of bending moment will
occur when the load is :

(A) Equally placed about the point

(B) When the point divides the load in the same ratio as it divides the span

(C) When the load is centrally placed

(D) When the tail end of the load is at the left end of the beam

If the moment ‘M’ is applied to the hinged end of a prismatic propped cantilever beam
then the moment at the fixed end of the beam will be :

The relationship between distribution factor used in moment distribution method
(dj) and rotation factor (rj} used in Kani's method is:

@) rj=-dj/2 ൫ rj=dj

The ratio of radiation reflected back by a surface to the radiation received by it is
called its :

(A) Radiation coefficient (B) Absorption coefficient

(C) Albedo (D) Bowen's ratio

A pipe 0.15 m dia taking off from a reservoir suddenly expands to 0.3 m at the end of
16 m and continues for another 15 m. If the head above the inlet of the pipe is 4.88 m,
the actual velocity at the exit, taking into considerates all the lossess 18,
