harmful friction is when friction can do harm or be a problem for example of this is if your skiing down a hill with grass you will have to much friction then you fall and get hurt :p
1. The soles of your socks wearing out 2. The gears in you care will wear down if not lubricated with oil 3. Holes in your jeans 4. Scraping your knee Harmful friction consists of two surfaces in motion, yet not in harmony with each other or one surface in motion against a fixed surface, which causes a wearing of one or both surfaces. Examples of harmful friction would be an abrasion to the skin from a person sliding on a rug or friction between a foot and a shoe creating heat and a blister in the skin of the foot. This is wrong. DONT USE THIS INFORMATION There are many examples of harmful friction. This can include the scrapes and cuts your encounter when falling down on the sidewalk. This can also be found in engines that are not properly lubricated causing them to heat up and malfunction.
Friction can be harmful or helpful when driving, no matter what time of year. For instance it is helpful when breaking and it is harmful between bearing surfaces. The loss of friction between the tyres and the road during winter can be disastrous.

Yes, friction CAN be harmful, depending on where it occurs. If you'd fall and scrub your knee, that's harmful friction. IF your shoes are chafing and yopu get a blister, that's harmful friction. In a machine, if a bearing becomes warm, that's harmful friction.
it can be harmful when you buy shoes and they are to tight and if your books and binders are really rough and you have a hard time sliding them into your back pack they will rub and cause friction
it can be harmful when rubbed against skin
it makes our shoes get blisters
