Question

A homogeneous triangular lamina has the vertices (0, 0), (3, 0) and (0, 3). Obtain the coordinates of the centre of mass of the lamina.

Answer 1

$x_c=\frac{x_1+x_2+x_3}{3}=\frac{0+3+0}{3}=1$

$y_c=\frac{y_1+y_2+y_3}{3}=\frac{0+0+3}{3}=1$ . So,

the coordinates of the centre of mass of the lamina $(1,1)$ . Answer
