Given that the density of aluminum is 5.26 slugs per cubic feet. Determine its density in SI units.

Determine the exact total hardness in units of mg/L as CaC03.Ba2+  contributes to hardness as well

2. In engineering, the modulus of elasticity is a way to measure how much an object deforms along an axis when opposing forces are applied among that axis. The formula can be expressed as E (F2-F)Lo where E is (82-81)A' %3D the modulus of elasticity, F is the axial force, & is a deformation measure, Lo is the original length of the object, and A is the cross-sectional area. Part A: Reaange the elasticity formula to find the cross-sectional area, A.

Measurements should be reported to the nearest 1000, 100, 10, 1, 0.1, 0.01,0.001 units, etc., depending on their variability and intended use. Using your best judgment, how should the following measurements be reported?a. Deformation of a steel specimen during the tension test (mm)b. Tensile strength of steel (MPa)c. Modulus of elasticity of aluminum (MPa)d. Weight of aggregate in a sieve analysis test (grams)e. Compressive strength of portland cement concrete (MPa)f. Moisture content in a concrete masonry unit (percent)g. Asphalt content in hot-mix asphalt (percent)h. Specific gravity of woodi. Distance between New York City and Los Angeles (km)j. Dimensions of a computer microchip (mm)
