We are currently producing Product Z using a very labor-intensive method.  The selling price of Product Z is $30 per unit, the variable expenses are $19.60 per unit, and the fixed expenses are $1,820,000 per year. I am wondering if it wouldn’t be better for us to automate the process for Product Z.  If we do, the variable expenses will drop to $16.00 per unit but the fixed expenses will increase to $2,940,000 per year.  The selling price will remain unchanged at $30...

3. A type of flexible polymer is polymorphic and experiences a change in crystal structure at a pressure of 10 atm. A junior engineer decides that its flexibility would make it very useful as a seal on the robotic arm of a research submarine. Describe (using three to four bullet-points) what might be observed in the first test of the submarine at high pressures and why (consider the worst case scenario).
