A mechanical engineer contributes to today’s society by giving people who don’t like changing their oil, and have someone else their oil changed. Also if someone looses a trainee or a drive shaft or your header is cracked they need someone to repair it if they cant, so they actually have a car to drive back n’ forth from work. If you broke down in the middle of nowhere we can have a tow truck and they bring it by the shop and we can fix it in a matter of days if not the hours. This is how my profession contributes to society.
OH!!! like this one time this guy called from literally the middle of nowhere and his motor mount had broken, which made his trainee fall out and made his motor set down like a foot from where it should be…So i brought it to the shop and i went out back to get a motor mount replaced the motor mount, bolts, and trainee and it was good as new
