it can create lots of heat
Noise is produced in machines due to friction.
when machines are used
when machines are used
the relationship between them is that the machines have friction that makes the machine goes
brakes
You provide lubrication.
Efficiency of the machine is reduced due to loss of energy by friction.
i donno :P
suppl Frequency
in clutch discs
Actually the good effect of friction is: if you drive a car you can make it stop, friction makes it stop. But the bad effect is: friction wears out machines so you can replace it. Hope it helps! :) Also with no friction the tires would just spin and go no place, and steering would be a problem.
Friction and windage causes mechanical loss in DC machines.
