Why are there no tri Jets?

Boeing had no reason to offer a Tri-jet as it developed the long and short versions of the 747.

Will Trijets come back?

Originally Answered: Will Trijet commercial airlines ever make a comeback? Very, very unlikely. There really is no reason for a Tri-jet. The development of the engines, air frames and airfoil design obviates the need for third engine and the increase in fuel, cost, and continuing maintenance.

Why are engines attached to wings?

Placing engines on the wing provides beneficial wing bending relief in flight. The further the engines are away from the fuselage the greater the wing bending relief so engines buried in the wing root provide little relief.
