Question

Explain why the tip of a syringe needle is sharps?

Answer 1

The needles are designed with the same general features, including a barrel, plunger, needle and cap. The end of the needle is bevelled to create a sharp pointed tip, letting the needle easily penetrate the skin.

The surface area is inversionally proportional to the pressure exerted.
When the surface area increases the pressure exterded reduces and vice versa
