Which one of the following statements is correct ?
In a plane truss, influence line values -
In a 4 m wide rectangular channel with 0.8 m depth of flow, a sharp-crested weir of 2.5 m length with its sill 0.3 m above the channel bed is fixed symmetrically across the width of the channel. Taking the flow to be free but with end contractions, what would be the discharge neglecting approach velocity effect? (Take Cd = 0.625)

A structural member carrying a pull of 700 kN is connected to a gusset plate using rivets. If the pulls required to shear the rivet, to crush the rivet and to tear the plate per pitch length are respectively 60 kN, 35 kN and 70 kN, then the number of rivets required will be
-
In the cantilever truss shown in the given figure, the reaction at A is
-
Following data refer to precise measurement of an angle A on the field :
(i) 2A = 20°10' - weight 2
(ii) 4A = 40°10' - weight 3
What is the most probable value of angle A ? -
A torsion member is fabricated from two concentric thin tubes. At the ends, the tubes are welded to rigid discs so that both the tubes are twisted as a unit. The radius of the outer tube is 2r and that of the inner tube is r. If the shear stresses developed in the outer tube is τ, then the shear stress in the inner tube will be.

Figure given below shows a fixed beam of steel: At the point of collapse, the value of load W will be
-
A mild steel flat of width 120 mm and thickness 10 mm is bent into an arc of a circle of radius 10 m by applying a pure moment 'M' If E is 2 x 105 N/mm2, then the magnitude of the pure moment 'M' will be
