Question 1

The magnetic bearing of a line OE was found to be 185 °. It was later discovered that station O had a local attraction of + 1.5 ° W. The magnetic bearing of the line OE, considering a magnetic a magnetic declination of 3.5 ° E shall be

Question 2

For an isotropic material, the relationship between the Young's modulus (E), shear modulus (G) and Poisson's ratio ( µ is given by

Question 3

A bar of varying square cross–section is loaded symmetrically as shown in the figure. Loads shown are placed on one of the axes of symmetry of cross–section. Ignoring self weight, the maximum tensile stress in N/mm² anywhere is

Question 4

Water is pumped from a well tapping an unconfined aquifer at a certain discharge rate and the steady state drawdown (X) in an observation well is monitored. Subsequently, the pumping discharge is doubled and the steady state drawdown in the same observation well is found to be more than double (i.e., more than 2X). This disproportionate drawdown is caused by

Question 5

A strut in a steel truss is composed of two equal angles ISA 150 mm × 150 mm of thickness 100 mm connected back–to–back to the same side of a gusset plat. The cross sectional area of each angle is 2921 mm² and moment of inertia (I_xx = I_yy) is 6335000 mm⁴. The distance of the centroid of the angle from its surface (C_x = C_y) is 40.8 mm. The minimum radius of gyration of the strut is
