Solution
Three examples to illustrate that friction is a necessary evil are as follows:
- Vehicles' tyres wear out due to friction, but without the friction, a vehicle won't be able to move on a road.
- Our shoes' wear soles wear out from walking and running due to the friction offered by the ground, but without the friction, we won't be able to run and walk.
- The machine parts in a machine wear out and get damaged because of friction, but without the friction between machine parts, the machine won't produce its desired output.
