4.2 A 200 m long sag curve is used under a grade separation structure. The curve joins an entry grade of - 3% and exit grade of + 5%. If the required vertical clearance is 5.5 m, determine the available sight distance over the curve. Assume driver eye height and dangerous object height of 1.8 m and 0.15, respectively. If the information available is not complete, please assume and specify a reasonable value and continue with the assignments.

A specimen of concrete column (200 x 200 mm) of 1.5 m long with 4 steel rebars (20 mm in diameter) inside with same length. If Ec = 21 Gpa, Es = 210 GPa, and free shrinkage strain = 0.0004, estimate the force carried by concrete and steel after shrinkage. If concrete tensile strength, ft = 5 MPa, will crack develop in this specimen?

A pipe, 900 m long and 200 mm in diameter discharges water to the atmosphere at a point 10 m below the inlet level. With an inlet pressure of 40 kPa gauge, the flow rate is 40 litres/sec. At a point half way between the pipe inlet and outlet, a new tapping is made from which water is taken at a rate of 18 litres/sec. To what value must the inlet pressure be raised in order to maintain the same...
