I am just not too sure how to start this equation. The answer was given (i.e. Vc = 3698 cm^3), but I just need to know the steps on how to get to the answer.
A sand core used to form the internal surfaces of a steel casting experiences a buoyancy force of 225.63 N. What is the volume of the sand core in cm cubed.
Steel Density: 7.82 g/cm^3
Sand Core Density: 1.6 g/cm^3
Fb = Wm - Wc
Wc = (Mc)(Gravity) & Wm = (Mm)(Gravity)
D = M/V
I have tried rearranging the equation: 225.63 N = Wm - Wc --> Wm = 225.63 + Wc
Then substituting it into the equation: Wm = (Mm)(Gravity) --> 225.62 + Wc = (Mm)(Gravity)
I then isolate the... I pretty much get lost after that.
Thanks for the help
