What are benefits of spring-mass model vs FEM and what are drawbacks?
1 Answers↳
Speed of execution among one of the benefits, drawback - each time resize/reshape model calibration needs to be done (takes computation time) to correctly match parameters like Young's modulus otherwise discrepancies up to tens of percents. Less
How many golf balls can you fit into a 747?
1 Answers↳
I explained the method I would use (equation-based due to ease of accessing parameters), then mentioned that had the problem dealt with for a mixture of balls of various sizes, then I would have modeled the situation and ran a simulation to find the best packing. Less

Mainly background questions that can easily answered.
You are given two ropes and a lighter. This is the only equipment you can use. You are told that each of the two ropes has the following property: if you light one end of the rope, it will take exactly one hour to burn all the way to the other end. But it doesn't have to burn at a uniform rate. In other words, half the rope may burn in the first five minutes, and then the other half would take 55 minutes. The rate at which the two ropes burn is not necessarily the same, so the second rope will also take an hour to burn from one end to the other, but may do it at some varying rate, which is not necessarily the same as the one for the first rope. Now you are asked to measure a period of 45 minutes. How will you do it?

Light both ends of rope 1 and one end of rope 2 simultaneously. When rope 1 burns out, light the other end of rope 2. Sure, I'll hire someone on the basis of answering this gimmicky question. Less
