yea

|dw:1332800247100:dw| Ok, the representative volume, dV is shown. How do I find the volume of that triangular chip?
anonymous
  • anonymous
we need the height (the dotted line) in terms of y. remember this is an isosceles right triangle.
anonymous
  • anonymous
can you find x in terms of y instead? |dw:1332800770452:dw|
anonymous
  • anonymous
x=y+h right?
anonymous
  • anonymous
remember, we're try to find the representative volume of this "chip": dV = (1/2)*b*h = (1/2)*x*x so you'll ned to find x in this drawing.|dw:1332800917466:dw|

you good up to here?
anonymous
  • anonymous
i am but i thought that 2y represents the full base
anonymous
  • anonymous
yes, it does. i just realizes we could get the volume using the x's. because volume = area of triangle * thickness
anonymous
  • anonymous
... would it be better to use a square cross section and divide that by 2?

ok... yw. replace that y in terms of x and now just integrate from x=-1 to x=1.
