A plastic gutter is designed to catch water at the edge of a roof. Manufacturers need to minimize the amount of material used to make their product. What is the best cross-section for a gutter? Options for cross-section are: 1. Triangular Shape 2. Rectangular Shape 3. Circular Shape I need to use optimization and calculus to solve this. Any working out you can show me would be very helpful.

Yes but you can't do optimization without equations

  • Australopithecus
These are pretty common equations

basically, i need to propose a value for the volume of each cross section, then optimize from there.

"Manufacturers need to minimize the amount of material used to make their product." what are the manufactures interested in optimizing?

these are elementary geometry equations

ok, all I know is that which is on the task sheet in the attachment. I have been given no further information. After reading the task sheet, you and I will be on the same level of understanding.

You need to use equations for surface area and volume because you are interested in optimizing the surface area to volume ratio
Australopithecus
  • Australopithecus
the manufacturer wants to use the least amount of material to achieve the most volume

which means i need to maximize the volume of the (lets start with number 1) triangle, but minimum TSA of the two sides. So say I propose a volume of 100 cubed units....

You need to relate both equations then take the first and second derivatives to determine the functions minimums and maximums depending on what relation you set your equation up

I have to go now. I wont be back on for a while but I'll continue work on the question. Thanks for the help so far, I'll get back to you on this later.
