Homework Statement
If a beam with square cross-section and very low density is placed in water, it will turn one pair of its long opposite
faces horizontal. This orientation, however, becomes unstable
as we increase its density. Find the critical density when this
transition occurs. The density of water is ρw = 1000 kg/m3
Homework Equations
3. Attempt at solutionTaking the centre of mass of the square cross section of the wedge as the axis and bouyant force to rotate the wedge about this axis we can equate torques. But i don't know how to do this
