Questions and Answers > How to read a chromatogram

  CHEMISTRY I73/4245/2 The word "chromatogram" means a plot obtained via chromatography. Fig shows an example of a chromatogram. The chromatogram is a two-dimensional plot with the vertical axis showing concentration in terms of the detector signal intensity and the horizontal axis representing the analysis time. When no compounds are eluted from the column, a line parallel to th ...[Show More]

A shaft is to be designed at the gear location (one critical point). The shaft span is 500 mm with two deep grooved ball bearings at the two ends. A 100 mm pitch diameter gear with 20-degree pressure angle is located at 180 mm from the left bearing. The transmitted power is 3 hp entering trough the gear and existing through a coupling at the right end. The shaft nominal rpm is 2000. Do not design the coupling. Assume the shaft material is AISI 1020 CD steel, the design factor is 1.2 and combined reliability is 99%.

A hurricane has just passed through a developing, small island country that has areas of high population densities. The country is devastated; homes are flattened and surrounded by or are under standing water. There is no clean running water available; roads are blocked and unable to accommodate vehicular traffic. The sewage system is broken and leaking large amounts of untreated sewage in many areas; the treatment plants are inoperable. There are large numbers of dead animals, both domesticated and wild. There are large numbers of live animals stranded or roaming. The death toll to humans is estimated to be in the tens of thousands. Gas and electricity are not operable. It will be months before minimal services can be restored.

Questiont67
write five pages about the following topic with refrences : When thinking about preserving the environment a lot of small variables get neglected in the process. These small variables when accumulated form a large impact on the environment. One of these variables is the leftover coffee residue in the coffee mugs. When taken in perspective the large population that consume coffee these residues start to threaten the environment on a larger scale than expected, when they end up in landfill or a sewage system that could cause it to reach the ocean water and pollute the environment. This issue needs a solution that gets rid of the threat on the environment. When this problem started to be noticed in Sidney where the coffee residue production rate reached 3000 tons per year, the engineers in Swinburne university of technology succeeded in finding a suitable application for these residues in paving the roads. The report will go through this subject more Thoroughly

Questionxcd
Consider the following diagram of the knee joint during the landing in a sprinting movement of a 60 kg individual with a leg of length 0.30 meters. The knee joint is flexed to 155 degrees. The quadriceps muscle produces 500 newtons of force and insert at a distance of 0.05 meters from the knee joint. The weight of the thigh acts from the center of gravity of the thigh, a distance of 0.21 meters from the knee joint, and produces a flexion torque. The gastrocnemius muscle can produce 600 newtons of force and inserts at a distance of 0.07 meters from the knee joint and would produce a flexion torque. What is the resultant angular acceleration of the knee in this example?

Exercise 1.2 Relative phase In Exercise 1.1, you have used two separate one-channel oscilloscopes to display the input and output waveforms. It was not possible to see the relative phase of the waveforms. A two-channel oscilloscope would have displayed the input and outputs curves in the same plot. Figure 14 shows such plots for inverting and non-inverting amplifiers. Figure 14. Inverting amplifier (left) and non-inverting amplifier (right); Yellow: input; Green: output. In order to verify that the inverting amplifier you built in Tinkercad actually inverts the signal, and the non-inverting amplifier does not, you will conduct the following experiment. (a) In the inverting amplifier circuit you built in Exercise 1.1, set R; and Ry to 1 kQ, increase the sine wave's amplitude to 6 V and change the frequency to 1 Hz. Change the op amp's supply voltages to +7 V and -7 V. Connect an LED's anode to the function generator's +ve terminal, a 1 kQ resistor to the LED's cathode, and the circuit's ground to the other end of this resistor. Add a similar LED/resistor network between the op amp's output and the ground. Run the simulation. State your observations and explain the behavior of the circuit. Include a screenshot in your report. (b) Repeat Part (a) for a non-inverting amplifier.
