give 5 ways on how friction can reduce or increased?Weegy:
This question interested me, I don’t know why maybe because I’ve never thought about it before. So I asked my engineer dad about it and as normal he answered the question with another question, what type of friction??? Evidently friction isn’t just friction and I’m gluten for punishment.
To make his very long answer short and understandable “I didn’t get half of it”.
Some types of friction that he explained and I remembered.
Static friction = non-moving surfaces
Kinetic friction = moving surfaces
Fluid friction = between layers of fluid that are moving relative to each other
Lubricated friction = like fluid friction but where a fluid separates into two solid surfaces
Skin friction/drag = the force resisting the motion of something passing through something air/water
Some ways he explained to reduce friction
1. Lubrication = self-explanatory
2. Reduction of contact point = if you reduce the area of contact you will reduce the amount of friction generated.
3. Mechanical engineering = wheels, bearings, Maglev technology
4. Low friction engineered Materials = evidently you can use certain materials or special coatings to reduce friction.
5. Polishing = smooth bearings work better than rough ones.
6. Streamline design = aerodynamics
Ways to increase friction
1. Don’t lubricate
2. Increase the weight/load
3. Heat = normally the change in materials as they are heated causes more friction not the heat itself.
4. Increase contact surface area.
5. Type of material = density, smoothness, elasticity
6. Design = increase drag
Hope that helps, sorry I didn’t understand or remember half of what he said.Auto Answered|Score 1Weegy:
