Answer 2

Scientific reasons for drawing pins having flattened heads.

EXPLANATION:

• A Drawing Pin has  fundamental additives: the Head, regularly made of plastic, steel or timber, and the Body, generally made from metallic or brass.  
• The Head is wide to distribute the force of pushing the pin in, permitting most effectively the hands to be used.  
• The drawing pin turned into invention and as a industrially produced item in america in the mid/late 1750s.  
• Moore defined them as a pin with a handle.  
• Later, in 1903, in Lychen, German clock maker Johann Kirsten invented flat-headed pins to be used with drawings.
• Drawing pins are a bit like nails with integrated hammers.  
• When you push at the big Flattened Head, the force you observe to the big flattened end is correctly magnified as it's focused into a miles smaller place at the tiny pin head.
