Bicycle vs. bicycle accident, who is at fault?

By13fggra

I'd like to know to what extent who is at fault. I'm riding on the right-hand bike path and keeping to the right. Another cyclist is coming from the other side and is staying very far to the left (from his perspective) on the same bike path. I keep riding, thinking he'll eventually swerve. He…

Force you only need to get your speed change, and it is proportional to mass and acceleration. If you apply the force over a certain distance, you promise Work.

In order to speed up your bike to a certain speed, you even have to do more work than without a bicycle (because of the additional mass). To keep the pace, you don’t need any more strength.

Now comes the big But:

There is a counterforce that reduces your laboriously reached speed: Friction between you and the way. And this can be greatly reduced, for example, with wheels (e.g. bicycles or e.g. roller skates) or also by suitable material combinations (e.g. metal on snow or ice, see skiing and ice skating).

The railway also makes use of this principle: metal on metal has significantly less friction than e.g. rubber on asphalt. This leads to less work to be done, but also to longer braking paths …

On the bike, the power is transferred and now googles and find the solution.

One does not apply the same force, but only about one third on flat roads for the same way. Someone used strength beforehand to make this road for you.

Bergauf looks different. If it becomes sufficiently steep, the runner is at some point in advantage. He has the same translation but less weight.

You don’t have to wear your body weight yourself.

You roll, which reduces friction.

This alone already leads to a higher speed, as you can see on wheels or scooters.

The pedal crank further optimizes the force and energy transmission, which also works at higher speeds with the gearshift.

Because the force you put in the pedals is converted into a rolling movement and is still present when you stop kicking. However, if you make one step forward, then all of you’ve been wasted in the step is gone.

In addition, it is not necessary to carry the body weight itself during cycling. That’s the saddle. The whole energy can be put into motion.

By stepping against the resistance of the pedal, the calf is more stressed, which can lead to hypertrophiic (enlargement) of the muscles. However, the effect of cycling on the calf muscles is not as strong as that of other exercises, such as wading.

How much faster is the ride by bike than on foot?

However, this is only valid if one selects a high gear and also assumes a wrong position. When I ride a bike, the saddle is at optimal height and it is like a somewhat cumbersome run from the movement, this should not be claimed anymore. Doesn’t matter if I see it wrong
