The tip of the needle is sharp. Explain why.

Answer :

Pressure is force per unit area. As the area decreases, the pressure will increase. The tip of the needle is sharp that is it has a minimum surface area than the rest of the needle. So when it is used in sewing, more pressure will be applied at the tip which helps in sewing through thick clothes.
