What are the pitfalls/problems of Tianjin Eco-City

1. Lab Procedure

The cross-section dimensions of the 6061-T6 aluminum bar are 0.512 in x 0.248 in.

Attach the lead wires of the gages to the strain indicator as a quarter bridge circuit. (Note: the black and white lead wires are the common leads.)

Enter the gage factor (GF=2.11) into the strain indicator.

Record the specimen number (1, 2, or 3).

Balance the strain indicator and note the zero readings. Load the specimen according to the table below and record the strain values in the table below.

IMPORTANT: DO NOT EXCEED A MAXIMUM PRESURE OF 2500 lbs.

IMPORTANT: DO NOT EXCEED AXIAL FORCE OF 2500 lbs.

2. Lab Report

For each strain gage, construct a graph with load on the y-axis and net gage readings on the x -axis. Indicate if the gage readings are linear with force.

At each load level:

• Calculate Poisson’s ratio based on the strain readings
• Calculate the axial stress
• Calculate the modulus of elasticity based on the individual readings of axial stress and strain

Determine the average value of Poisson’s ratio and the modulus of elasticity. For 6061-T6, find accepted values of Poisson’s ratio, modulus of elasticity, and the yield stress.

Imagine you need to design a jar test experiment to determine the most efficient removal of phosphate from

water, e.g., precipitation from a treated wastewater. For each of the following potential wastewater effluent

phosphate requirements, recommend a chemical dose to achieve these requirements. Be sure to explain why

you are recommending these doses.

a.1 mg P/L

b.0.5 mg P/L

c.0.1 mg P/L

The dry weight of a natural stone sample is 336 g, the water-saturated weight is 340 g, and the water-saturated sample is 196 g in water. The volume of the 50 gr powder sample obtained by grinding the same stone is 18.7 cm3 measured at the picnometer. Calculate the unit weight, specific weight, and weight and volume water absorption rates of this stone.

Explain in some detail what has changed, if anything, of your expectations of the attitudes and behavior of an ethical engineer.
