What places need friction?
If you were roller-skating you don't need friction because it slows you down. Well you want friction between the wheels and the floor (so you do not slip sideways) but not between the wheel and the axel (thats why you have ball bearings there to reduce rolling friction). If you are ice skating you do not want friction between the blade of your skates and the ice.
What would happen if the coefficient of friction between the tire and the pavement increased greatly?
Nothing. That's exactly what you want. When your coefficient of friction decreases too far, you need new tires.
Does more friction means more work?
yes. to have friction you need more movement between what ever is making the friction which then brings you more work
Example of where you need friction?
The breaks on your car require friction to make the car stop. Friction between the souls of your shoes and the ground keeps you from sliding.
Why do you need friction on a surfboard?
Without friction, your feet would just slip right off.
Where is friction needed in a backhoe loader?
You would need friction between the tires or tracks and the dirt the tractor is sitting. If you have extended legs, you need friction between the pads and the ground. You would want friction in the brakes. A clutch also relies on friction. Technically you could "dig water", but if you are trenching, then one needs friction between the dirt particles. It is also handy to have friction in your seat, steps, and controls.
Jack is going skiing does he need high or low friction between his skis and the snow?
low friction
If you were riding a bike where would you need a lot of friction?
Between ground and tires and between brake pads and moving surface.

How do friction affect?
We would need to know what the friction is to affect to respond to this question.

Do you need friction for typing on a keyboard . why?
Because without friction, it would not be successful when typing!
What would you need if there was no more friction?
It would be impossible for you to do anything.

What places don't you need friction on a sleigh?
Between the runners and the snow.
