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?

Solutions

Expert Solution

Free body diagrams for each of the crates are drawn.From which we get the force equations and on solving them,we get the maximum force we can apply to the lower crate

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?
