You are considering two columns with identical dimensions. One is constructed out of steel, the other aluminium, which will buckle at a smaller load? The euler formula for critical buckling force for column, pin jointed at both ends is given by Pcr = pi^2 EI/ L^2 if the end of the column are constrained to prevent rotation, how will the buckling force change?

Suppose there are two blocks constructed so that one is twice as massive as the other but they both are the same size and shape. If they are both dropped into free fall on, say, the moon, where there is no atmosphere, would they fall at the same rate? If they were dropped on Earth would they still fall at exactly the same rate, would the heavier one fall twice as fast, or something different? Explain what you think happens...

Assume that you have two cylindrical steel samples with 1 in diameter, one made out of AISI 1045 and another one made out of AISI 4140. You austenitize and quench both samples in oil. Then you cut a section and measure the hardness at the center of each sample. Would you expect to get the same results? Explain your answer.

A steel industry emits, other harmful pollutants , CO. There are 8 identical firms in this industry. Four of them are located near a city( urban area) while four of them are located in the country ( rural area) . They can install filters ( srubbers) in their exhaust to clean up part of their emissions. Their abatements costs related to CO clean up are described by MACi= 400- 8Ei, where i = 1,2,....8 . The emission of CO are...

Two gas cylinders are identical. One contains the monatomic gas neon (Ne), and the other contains an equal mass of the monatomic gas krypton (Kr). The pressures in the cylinders are the same, but the temperatures are different. Determine the ratio KEAvg,krypton / KEAvg,neon of the average kinetic energy of a krypton atom to the average kinetic energy of a neon atom. KEAvg,krypton / KEAvg,neon = Need equation with numerical answer!! Thanks

Three identical 4 kg crates are stacked one on top of the other. You want to accelerate them as much as possible by pushing on the lower crate, but the forces of static friction between the surfaces of the crates max out at 25 N. What is the maximum acceleration you can achieve before the upper crates start to slide? And what's the maximum amount of force you can apply to the lower crate?
