Idk it might use magnetic brake pads. I have used them in other fields & they are pretty nifty. The ones I used created eddy currents & had not mechanical wear. For my project the mechanical brake had a ~10 year lifespan while the magnetic brake could last ~50 years. Also the mag brake was only 30% more expensive but didn’t need maintenance & would be significantly cheaper if you took the lifespan of the project.
Dog walking or other skill based teaching/tasks. You might need some small things like poop bags or something else. In the past I did dog walking & that is easy to start. Then I expanded to helping train & other tasks around taking care of dogs. That’s just what I did but you can choose something else you like such as music lessons.
I think there is some more nuance here then all restocking fees are bad. For some businesses that sell items that are custom made or have so many varieties that they are practically custom parts. So when an item like this is returned it can’t be sold at the same amount & storing the item until it sells has a cost. So to encourage customers to be certain of their orders a restock fee is used on some items to stop customers from ordering testing then returning what they don’t like.
If you bring up Amazon’s restocking fee your right those guys are assholes who try to squeeze as much cash out of everyone.
In the real world yes-ish. In the case of a a roller coaster or car the eddy currents bring the speed to near 0 & the rolling friction brings it to a complete stop. The issue is an eddy current braking system can’t keep something at rest. That’s why the roller coaster has a physical brake to keep the ride in place when people are getting on. There are other types of magnetic brakes/ contactless brakes, I just don’t know much about them. My company used the eddy current brakes to limit fall speeds to a safe level if a specific part fell during an emergency.
