Solution
Water flows through a 100 m diameter pipe with a velocity of 0.015 m/s. If the kinematic viscosity is 1.13 × 10–6 m2/s,the friction factor of pipe material is

Solution
A CO tri-axial fest was performed on a saturated sand at a cell pressure of 100 kPa. The ultimate deviator stress was 350 kPa and the pore pressure at the peak stress was 40 kPa (suction). What is the internal friction

Solution
An open ended steel barrel of 1 m height and 1 m diameter is filled with saturated fine sand having co-efficient of permeability 10–2m/s. The barrel stands as a saturated bed gravel. The time required for water level in barrel to drop by 0.75 m is

Solution
The figure shown below showing two flow lines for seepage across an interface between two soil media of different co-efficients of permeability.If entrance angle α = 30°, the emt angle α2 will be __________.

Solution
Using Terzaghi theory, determine the ultimate bearing capacity of a strip footing 1.5 m wide resting on a saturated clay (Cu= 30 kN/m2, fu = 0, rsat= 20 kN/m3) at a depth of 2 m from the ground level. If water table rises by 1 m, calculate the percentage reduction in the ultimate bearing capacity.

Solution
Consider the following statements related to reinforced concrete design and identify whether they are true or false.
1.Curtailment of basis in the flexural tension zone in beams reduces the shear strength at the cut-off sections.
2.When a rectangular column section is subject to will at eccentric compression, the neutral axis will be parallel to the resultant axis of bending.
The order for the flexibility matrix for a structure is
The strain energy stored in member AB of a pin joined truss shown aside when E and A for all members is
-
Solution
Strain energy of base AB, U = \(\frac{F^{2}1}{2AE}\)
FAB = 0
∴ uAB = 0
A rod PQ of length L and flexural rigidity EI is hinged at both ends. For what minimum force F is expected to buckle?
