Chemical and material enginnering
The Archimedes principle was the standard that researchers were utilizing to measure the density of the nc Cu sample (Lu, Lu & Sui, 4128). The density of the sample was 8.03 g/cm3, which is indifferent from that of pure Cu, which is 8. X-ray diffraction and HRTEM analysis were essential in determining thee microstructure of the Cu sample. The determination of the nc Cu samples thermal characteristics was through differential scanning calorimetry (DSC). Plastic deformation of Cu was through

Surface engineering technology used in industry for surface modification( i.e surface treatment-surface thermo-chemical tratment or surface coating )
The nitride layer on the surface of the metal makes it expand, thus creating large, compressive stresses that in turn increase surface hardness and improve fatigue strength. In addition, the process also results in steel that has a reduced friction coefficient. Nitriding is, therefore, the best method to use when developing surfaces that are intended to minimize friction such as crank shafts and ball bearings.This process involves the dispersion of carbon atoms into the surface of the metal.

Investigate the root causes of major Engineering disasters that have occurred since 1800
Frankel (2010) observed that the Chernobyl reactor was designed to use graphite moderators that were typically unsafe, in addition to use of graphite rods. As a result, any possible loss of water in such a RBMK reactor posed great danger.Contrary to the operations of Pressurized Water Reactors (PWR), any water that circulates in the pipe network is only required to serve the purpose of cooling the reactor core only and not to moderate the core and cool it (Frankel, 2010). In PWR reactor cores,

Renewable energy
Wind energy has the second largest potential. It proves to b more cost efficient as compared to the solar energy. Wind energy rotates the turbines that power the generator with the help of wind. Wind energy can reach remote region where transmission lines seem unrealistic. The operational cost of the wind energy is just a fraction. The area below the wind turbine can be used for irrigation and other purposes (Ryan).The major disadvantage of the wind energy is that it requires large capital

Gear Ratios ( Mechanical engineering )
The complete machine should include a battery connected to a DC motor by electricity wires-probably made of copper, the motor connected to the gear system by use of the sprocket and the gear system connected to the lifting system by the output sprocket.The lifting of the weights is indirectly proportional to the number of gears used, and sizes of their sprockets. Use of large gears will enhance little motion and lifting of little weight while the use of small gears brings about a greater force.

The costs and benefits of harnessing power to generate electricity from wind energy
Alternative approach, the following analysis will promote an understanding of some of the pros and cons of the utilization of solar energy (Williams, 2014).Firstly, it should be noted that a large majority of energy (electricity) is generated by coal plants. These coal plants are inherently a dirty way of creating electricity; due to the fact that they burn the fossil fuel coal as a means of generating that in turn drives turbines which produce electricity.
