WebNov 28, 2016 · The density ρ (mass per unit area) of a semi-circular lamina Ω of radius a is proportional to the distance from the centre of the circle. Find the centre of mass ( x ¯, y ¯) of the lamina, taking x ¯ = 0 by symmetry, given m y ¯ = M y = ∬ Ω y ρ ( x, y) d A and m = ∬ Ω ρ ( x, y) d A where m is the mass of the lamina. Use Planar polar coordinates. WebA circular disc of mass M and radius R is rotating about its axis with angular speed $${\omega _1}$$ . If another stationary disc having radius $${R \over 2}$$ and same mass M is droped co-axially on to the rotating disc. Gradually both discs attain constant angular speed $${\omega _2}$$ the energy lost in the process is p% of the initial energy.
