Question

Explain the science related with Thanjavur doll stable equilibrium

Answer 1

Answer:

The Thanjavur doll is a type of traditional Indian bobblehead or roly-poly toy made of terracotta material. The centre of gravity and total weight of the doll is concentrated at its bottom-most point, generating a dance-like continuous movement with slow oscillations.[1] These toys are traditionally handmade, finished with detailed, painted exteriors. They have been recognized as a Geographical Indication by the Government of India as of 2008-09.

Answer 2

The science is related to a stable equilibrium where the doll regains its shape.

• These dolls have detachable heads that shake when disturbed. Greater size and weight are found in the lower body than in the head. Watching them move as they nod their heads in the breeze is fun.
• The bottom of the doll, where there is more weight, is where the Center of Gravity is located. The doll is resistant to falling over. It quickly regains its shape.
• From the stable equilibrium, we may deduce that an object will fall if the centre of gravity crosses the weight distribution line.
• That explains why the Thanjavur doll's centre of gravity is positioned slightly off the mass's centre of mass and downward.
• Because of this, the centre of mass crosses the weight distribution line but not the gravity line. The object, therefore, reclaims its own
