Question

Why friction damages machine

Answer 1

• Since friction is a resistive force which slows down the moving object hence, it can cause serious damage as well. ... Thus in machinery the force of friction acts then this can produce heat and this can cause fire or it can burn the machinery. And then moving parts wear off rapidly due to friction.

Answer 2

Answer:

friction is an opposing forces which opposes the motion of objects

when friction works then it produces heat. heat is responsible for damaging the machine because when we heat metal then due to heat it becomes soft and get damage easily
