Heat Treatment and Qualitative Metallographic Analysis Lab ME 3228: Mechanics & Materials Laboratory Summary Comparing a material’s initial treatment and the microstructures that are formed from different processes‚ an engineer can accurately understand why certain treated materials of the same family can be stronger than another. In this experiment annealed and cold-worked specimens of AISI 1018 STEEL are used‚ along with a Hardness tester‚ a grinding and polishing process‚ and a micrograph

Heart of Darkness vs. Secret Sharer Does Conrad base the character development in his stories on his own explorations? Based on the similarities of “The Secret Sharer” and “The Heart of Darkness”‚ yes. Conrad’s main characters are both young‚ non-tested men who are exposed to the uncivilized human nature. There is also another character that is allows an insight into the main characters life. A lot of change takes place inside these characters throughout the story. Conrad develops his main characters

Beat the heat with aircon repair Summer times can be difficult to manage in the hot regions and this calls for a nice chilled breeze of the air conditioner. While this may be the best prospect at this time‚ the problem comes with the appliance itself. Air conditioners just like any other electronic appliance are prone to problems and malfunctions. The malfunctions in this case can be quite bad considering how complicated the appliance is and this means that it requires professional help and not a

CRITICALLY EVALUATE THE FACTORS INFLUENCING THE GLOBAL HEAT BUDGET - 40 MARKS The global heat budget is the balance between incoming insolation‚ and outgoing radiation from Earth. There are many factors that influence this heat budget‚ some of which are more important than others. In this essay I am going to describe and explain each factor involved. Insolation is the incoming energy from the sun in shortwave ultraviolet (UV) radiation. The distribution of insolation over the Earth’s surface

In this experiment‚ the Independent Variable was the heat lamp‚ and the dependent variable was the temperature of the soil‚ because the temperature varied based on whether the heat lamp was turned off or on‚ and whether there was extra water added or not. Our hypothesis was proven correct‚ because the dry soil’s temperature was hotter than the damp soil’s temperature when the heat lamp was on‚ but then it decreased when it turned off‚ while the damp soil’s temperature remained the same. This is because
