Question 1

An insulated tank contains half liquid and half vapor by volume in equilibrium. The release of a small quantity of vapor without the addition of heat will cause what?

Answer 1

Evaporation of some liquid in the tank

Question 2

The Euler formula for columns deals with:

Answer 2

Elastic buckling

Question 3

Cold-working produces what results?

Answer 3

Recrystallization temp decreases, ductility decreases, slip/twinning takes places and grains become elongated

Question 4

The Euler formula for columns deals with:

Answer 4

Elastic buckling

Question 5

Critical radius of insulation is the radius which heat loss is?

Answer 5

Maximized

Question 6

What does an amorphous material mean?

Answer 6

No crystalline structure AKA glass

Question 7

Ferrous metals e.g. steel contain iron, while non-ferreous metals e.g. aluminum and gold don’t contain iron. And by iron, we mean the periodic table element of Fe.

When thinking of ferrous metals, think fe-rrous.

What is a reason for selecting a non-ferrous metal over a ferrous metal in an application?

Answer 7

Low weight, corrosion resistance, electrical conductivity, thermal conductivity, non-magnetic properties.
