a) Draw a 2D element and show the dofs (degrees of freedom). Draw all the 2D elements used in Strand7. Explain the differences between these elements in terms of the no. of nodes and interpolation/shape functions used.
b) A 8 m x 8 m plate (in the xy plane) with 8 mm thickness, is fixed at all the edges and is loaded by a pressure loading of 4 kN/m2 in the downward (-z) direction. The plate is made of steel (E = 200 GPa, density = 7850 kg/m3). Explain the steps involved in setting up a Strand7 model for this problem. Your explanation should include how the given input data for this problem will be used in Strand7 modelling. Explain how you would determine the maximum deflection from the Strand7 output.
For the truss shown in Fig 2, determine the nodal displacement and member forces using the stifness method for all elements of the truss. Assume for each member A = 0.0015 m2 and E = 200 GPa
5. Two 400 g blocks are connected by a rigid rod. The Blocks can rotate freely at the ends
of the rod, so the rod does not apply any moments to the blocks. The blocks are in
contact with the wall and floor, and can slide without friction. The system is released
from rest when X=24cm and Y=18cm. Ignore the mass of the rod. What are the initial
accelerations of Block A and Block B just after being released?
Hint: See Assignment 4, Problem 2 for help getting a relationship between the
acceleration of Block A and the acceleration of Block B.

Assume that the organic matter (VS) in the sludge contains 10% N and that the ratio of VS/TS in sludge is 0.85. A) How many mg/L of N are removed from the wastewater due to assimilation? B) If the raw wastewater contained 50 mg/L total N, what percent was removed via assimilation?

The nitrifying bacteria numbers grew to significance by Day-8.There is a lower cBOD curve and an upper nBOD curve. BOD₁ = UBOD (1− e−k₁t) A) What is the rate constants k for cBOD? B) What is the rate constants k for nBOD? C) Why aren't nitrifiers prevalent in the raw wastewater? Treatment ponds have long hydraulic residence times (HRTs), so nitrifiers are a significant part of the microbiome. D) Sketch a 50-d BOD curve similar to the above, but for a pond effluent sample.
