The first phone interview was about comparing two concept of material: Young's Modulus and Yield strength. And how the properties will affect the user experience on their product.
If a 10 X 10 X 2 mm part is being machined by CNC, what is the tolerance requirement for the width.
Between rubber and metal, which one has higher stiffness?
Two products made in same geometry but in copper and iron, which one has better heat conduction
Cantilevered beam bends 10mm and breaks. How to make it stronger?
You have two metal spheres that look and feel exactly the same from the outside but are made from different metals - describe non-destructive methods to determine what the materials are.
You have 4 beams. Beam 1 has a 3*3 cross-section. Beam 2 has a hole in the middle so the cross-section is 8 units in area. Beam 3 is an I-beam with thickness in 1 everywhere. Beam 4 is the H-beam which is the same in cross-section as Beam 3. Which beam is the strongest?
