stress (repeated or fluctuating). Eliminating any one of the above three requirements will stop the fatigue process. 2. Describe the three stages of fatigue in metals. The three stages of fatigue in metals are: Stage 1: Crack Initiation – Movements of dislocations resulting into slip line and slip planes. It will begin at the point where the local tensile is a maximum. Stage 2: Crack Propagation (Fatigue Zone) – Cyclic tension stresses spread the crack. If the part breaks in one application of

Once image is focused the objective lens may be changed and you can then begin to view the specimen within a higher power of magnification. 2. Describe the purpose of each of the following microscope parts: ◦ objectives- to magnify the view of each specimen ◦ rheostat Wheel- regulates the light intensity ◦ course and fine adjustment knobs- coarse knob is used for focusing the specimen

Title: Rate of transpiration I found interesting to know how different environmental factors affect the rate of transpiration. There are different environmental factors‚ such as light intensity‚ humidity‚ wind and temperature that affect the rate of transpiration. Transpiration is a topic 9 in our Biology higher level book. I have read all the information through this chapter and researched some extra information. Based on this information that I had known I decided to take experiment of environmental

The majority of my results produced the expected bell curve on my graph. However‚ I believe due to human error the results were incorrect between temperatures of 60Ëšc and 80Ëšc causing this area of my graph not to follow the pattern of my initial prediction. I have also noticed that the highest rate is at a slightly higher temperature than I expected‚ though this may be due to the large difference in temperature between each sample. As the temperature was increases the molecules were
