Free body diagram and Forces

  1. Feb 17, 2009 #1
    Im working on the problem below and trying to figure out if I have the right approach. Im checing to see if my free body diagram is correct. Also if finding the vertical force exerted on the bottom of the tank is just the differenence of the bouyant force and wieght of the cylinder as showin in my work. thanks

    would I need to take into consideration the depth of the water?....or just the weight of the cylinder and the bouyant force?

    Hi Jason,
    Your calculations look fine. In calculating the buoyant force, the depth of the water isn't a consideration. Archimedes principal looks only at the weight of the fluid displaced by the solid object, not the pressure of the fluid.
