Chapter 36, Problem 1RQ
Why are carbon dioxide emissions a concern?
Expert Solution & Answer
To determine
The concern for reasons behind emissions of carbon dioxide.
Explanation of Solution
The most basic and common element of life on earth is carbon. A colorless gas having density sixty percent higher than dry air generated upon burning of fuels. Human bodies are made up of carbon including the air we breath and crops we grow. The air we breathe, carbon present is used by plants for the process of photosynthesis.
Carbon dioxide is formed from the burning of fossil fuels. Carbon dioxide emission has caused greenhouse effect one of the serious problems in polluting the environment. It absorbs the heat from atmosphere and making the earth surface warmer. This has increased the average temperature by fifty-nine-degree Fahrenheit. Emission of carbon dioxide is released into atmosphere when any fossil fuel containing carbon is burnt. Plants absorbs carbon dioxide to build their and thus bringing level of carbon dioxide from atmosphere.
So, emission of carbon dioxide is really a concern as it is the major cause greenhouse effect.
Due to emission of carbon dioxide the water of oceans is becoming more acidic. Thus, affecting the life of water animals. Global warming is result of excess amount of carbon dioxide. It has alone contributed sixty-six percent in global warming. Excessive emission of carbon dioxide has brought following changes in atmosphere:
- It has increased the level of seas, people living in coastal areas life has be endangered.
- The supply of water has shrunken as the demand is increasing.
- It has brought some geographical changes.
- It has increased the severe weather conditions. Storms are becoming more frequent.
- It has affected the food supply change also.

The single degree of freedom (SDOF) system that you studied under free vibration in Assignment #3 - Laboratory Component has been subjected to a strong ground motion. The acceleration at the base (excitation) and the acceleration at the roof (response) of the SDOF system was recorded with sampling rate 50 Hz (50 samples per second, or dt= 0.02 seconds). The file ElCentro.txt includes the two columns of acceleration data. The first column lists the acceleration at the base of the SDOF system. The second column lists the acceleration at the roof of the SDOF system. (a) Plot the time histories of the recorded accelerations at the base and at the roof of the SDOF system. (b) Compute the acceleration, velocity and displacement time histories of the roof of the SDOF system subjected to the recorded base acceleration using the Central Difference method. Plot the accel- eration, velocity and displacement time histories. Plot the restoring force, the damping force, and the inertia force time…

- Assume multiple single degree of freedom systems with natural periods T ∈ [0.05, 2.00] seconds with in- crement of period dT = 0.05 seconds. Assume three cases of damping ratio: Case (A) ξ = 0%; Case (B) ξ = 2%; Case (C) ξ = 5%. The systems are initially at rest. Thus, the initial conditions are u(t = 0) = 0 and ̇u(t = 0) = 0. The systems are subjected to the base acceleration that was provided in the ElCentro.txt file (i.e., first column). For the systems in Case (A), Case (B), and Case (C) and for each natural period compute the peak acceleration, peak velocity, and peak displacement responses to the given base excitation. Please, use the Newmark method for β = 1/4 (average acceleration) to compute the responses. Create three plots with three lines in each plot. The first plot will have the peak accelerations in y-axis and the natural period of the system in x-axis.

- A transformer that is 10 cm long, 6.2 cm wide, and 5 cm high is to be cooled by attaching a 10 cm by 6.2 cm wide polished aluminum heat sink(emissivity=.03) to its top surface. The heat sink has seven fins, which are 5 mm high, 2mm thick, and 10 cm long. A fan blows air at 25 degrees C parallel to the passages between the fins. The heat sink is to dissipate 12W of heat, and the base temp of the ehat sink is not to exceed 60 degrees C. Assuming the fins and the base plate to be nearly isothermal and the radiation heat transfer to be negligible, determine the minimum free-stream velocity the fan needs to supply to avoid overheating. Assume the flow is laminar over the entire finned surface of the transformer.arrow_forwardI need a mechanical engineering expert to solve this question,no Ai pleasearrow_forwardCan you give me the meaning of Combination spanner and Give Examples of Spannersarrow_forward
