Question

Find the centre of mass of a L-shaped lamina (a thin flat plate) with dimensions as shown. The mass of the lamina is 3 kg. plzzz no links

Answer 1

Lets suppose each  square lamina has a mass of 1 kg. having COM at (1/2, 1/2) (3/2, 1/2) (1/2, 3/2)

COM of L shaped lamina will be
x= m1x1  + m2x2 + mx3/ m1 + m2 + m3
by putting the values we will get x= 5/6m

y = m1y1 + m2y2+ m3y/ m1 + m2 + m3
y= 5/6 m
