Question

Who invented the steam locomotive engine?
(a) James Watt
(b) Abraham Derby
(c) Faraday
(d) George Stephenson

Answer 1

Hint: A Steam locomotive is a Locomotive whose primary power source is a steam engine. These locomotives are fuelled by burning combustible material like coal, oil, or wood. Although these mechanical systems are now extinct steam technology lives in people’s hearts and locomotives like this still run as tourist attractions.

Complete answer:
A steam engine is a machine that burns coal to release the heat energy it contains so it’s one of the examples of a heat engine. There are four major parts to a steam engine.

(ii) a boiler which is full of water that the fire heats up to make steam.
(iii) A cylinder and piston
(iv) A machine attached to the piston
First was the evolution of the railroad, the combination of the steam locomotive, and a permanent travel way of metal rails. The first fully timetabled railway service which was Liverpool and Manchester Railway was designed by George Stephenson, and the locomotives were the work of Stephenson and his son Robert, The first locomotive being the Famous rocket, won a competition held outside Liverpool. Locomotives increased rapidly in size and in power, but the basic principles remained the same which was by Stephenson.

So, the correct answer is Option (d).

Note: James watt - He is remembered for his improvements to the steam engine.
 Abraham darby- He brought with him a big idea- a patent for casting iron in sand molds. Faraday- His biggest breakthrough was his invention of the electric motor.
