Selection of the most suitable material for impact dampener in presses. Size doesn't matter
LP 5. (20 pts) It is known that most of the mass of galaxies is some exotic material that doesn't interact with light or normal matter. Let's assume that this "dark matter" is due to a new elementary particle---alaskonium. Like Alaska in the winter, alaskonium in the galaxy is cold and dark. We will assume that alaskonium is a fermion and that it is so cold that it is degenerate; a gravitationally bound, nonrelativistic, degenerate gas. Take the total mass...
(a) Briefly explain three (3) methods of material selection. (3 marks) (b) With suitable example, explain three (3) types of design (6 marks)
what is self/selection bias, study design most prone to the trap. How does self selection impact the study outcome how to control for the trap

suppose that management increases the size of its plant. the most likely impact on total and marginal products of the other inputs is that both will increase True or false
Selection of materials One of the most challenging task of materials engineer is the proper selection of the material for a particular job, e.g., a particular component of a machine or structure. An engineer must be in a position to choose the optimum combination of properties in a material at the lowest possible cost without compromising the quality. A number of questions need to be answered before a decision can be made as to the specification required of a material...
Estimate the number of protons in the universe. Assume that most of the matter is due to the stars, which are made mostly of hydrogen. There are roughly 1012 galaxies in the universe, and their average size is that of the milky way which has about 1011 stars, where the average mass is the one solar mass (The mass of our sun is about 1.99 × 1030 kg, mass of hydrogen is about 1.67 × 10-26 kg)
