A concrete mix was designed for thin core walls in a tall building. A 28-day strength of 32 MPa is required. The exposure classification for durability purposes is for B2 and C. One hundred laboratory test results on the controlling mix show a standard deviation of 5.3 MPa (k=1.65). The density of uncrushed coarse aggregate is 2850 kg/m³ and its dry rodded density is 1600 kg/m³ and the maximum size to be used is 10 mm. The density of fine aggregate is 2750 kg/m³ and its fineness modulus is 3.0. The high early strength cement used has a density of 3150 kg/m³.

Find the weight (in kg) of cement, water, fine and coarse aggregate for this mix, required to make a 2.4 m high x 1.2 m wide x 120 mm thick concrete wall using the ACI Method.

If a cylindrical steel pressure vessel has a 400-mm inner radius and 8-mm-thick walls. Find the change (mm) in the inner radius when the vessel is pressurized to 1.2 MPa. Use E = 200 GPa and v = 0.3 for steel.

It is believed that the design of appurtenances in the stilling basin can reduce the basin length by 70- 80%. Give comments on this statement.

What does it mean for a professional to uphold a standard of due care? What norms and standards should an engineer look to, in determining what constitutes "due care" in a given situation? Why is it hard to have universal and precise rules that tell us exactly what "due care" requires in a given situation? How does an engineer know the difference between practicing due care, and being negligent?
