Question

Explain the method to find the centre of gravity of a irregularly shaped lamina.

Answer 1

Answer:

$\large\mathbb{\underline\purple{ANSWER}}$

Centre of Gravity of irregular lamina - definition

Take a lamina with three holes near the periphery of the lamina, now suspend the lamina through them, one by one. Draw a line of equilibrium for each suspension point. The point of intersection of these three lines would be the centre of gravity.

Answer 2

The center-of-mass of an irregular shaped lamina is found by supporting it from various points. The lamina is hung from any of its suspension points with the plumb bob hanging from the same. A chalk line is drawn along the vertical plumb line. This is repeated from one or two other suspension points.
