I need help with theses WIT QUES
Suppose you are designing a beer mug. Make a mechanical drawing of a mug on a graph paper. Do not sketch. Use rulers and compass to draw. Label the scale of your drawing. You may use 1:1 scale. Make top view and side view. Label dimensions and tolerances: height, width, inner diameter, outer diameter, wall thickness of the mug. Label material Suppose you are to design a skateboard and you are given a roller bearing with the outer diameter 1.0000+0.0000/-0.0004, what is the diameter of your bearing housing so that the bearing can seat correctly inside? Which is true? (A) Steel is made in a pure crystalline form. (B) Steel is made in a polycrystalline form. Explain why polycrystalline steel is stronger. What impurity (element) in the steel that would make steel stronger? Math: A chicken and a half lay an egg and a half in a day and a half, how many eggs will 6 chickens lay in 7 days? This problem is due to Dean Jerry Rosenberg of PSME. To become an engineer, you studied 3 hours a day more than other majors because you have to take math, physics, and engineering courses. Each year have 9 months of school (30days/mo). Suppose you complete the engineering degree in 4 years. Suppose you made $30k more than your counterpart each year. You work for 45 years before you retired. How much money would you "pay yourself" in $/hr for those extra time (3hrs/day) you put in for 4 years?Explanation / Answer
For number 1, cant help. Just draw a cylinder to full scale, dumb question.
for 5, a tolerance for a bearing pocket - this is an unrealistic bearing pocket - too loose, its held to about 10 microns, typically, theyre held a lot tighter than that. To tolerance it, -0.0000/+0.0004, this is standard ISO tolerancing for line-to-line fits.
10, steel is a polycristline form as steel is made of more than one element. polycrystalline steel is stronger based on carbon content, that is the impurity - carbon. Also, chromium and molybdenum can be added in the case of 8620. The first two numbers state the alloy, the second two state the carbon content.
