Why does a porter bend forward while carrying a sack of rice on his back ?

Text Solution

Verified by Experts

When a porter carries a sack of rice, the centre of gravity shifts from the body's line of gravity. However once the porter bends, the centre of the gravity re aligns with body's line of gravity and making the porter balanced.
