The R.L. of ground water table on the sides of a valley is 1505 m whereas R.L. of the stream water is 1475 m. If 60° slope consists of pervious soil between R.L. 1485 m to 1500 m, the gravity spring may be expected at the point of reduced level
Correct Answer: 0.1 L from the centre edge of column
3. If At is the area of steel cross-section, t is working stress, L is width of road and W is weight of slab per square metre, the spacing of the tie bars for a longitudinal joint, is
5. A vertical rod PQ of length L is fixed at its top end P and has a flange fixed to the bottom end Q. A weight W is dropped vertically from a height h(< L) on to the flange. The axial stress in the rod can be reduced by
Options
A. increasing the length of the rod
B. decreasing the length of the rod
C. decreasing the area of cross-section of the rod
D. increasing the modulus of elasticity of the material
6. If R is the reaction on the bearing plate, the minimum moment of. inertia of the bearing stiffener provided at the support of a plate girder of overall depth D, the maximum thickness of the compression flange T, carrying total load W, is
7. If L is the length of the transition curves provided on either side of a circular curve of radius R, the maximum angle of deflection with tangent for the junctions of the transition curve and circular curve, is
8. If P is the load applied to a bracket with an eccentricity e, the resisting moment F exerted by a rivet at a distance rn from the centre of gravity, is
10. If M is the moment due to a couple in a bearing plate whose width is b and allowable bending stress is P, the thickness (t) of the bending plate of the column splice, is
