AI Thread Summary
The discussion revolves around building a battery-powered miniature cable car using a specific 9V motor. Participants emphasize the importance of understanding the motor's specifications, including the mass of the cable car and the friction involved. The creators plan to use gears but seek advice on the optimal number and configuration. They aim for fast, horizontal movement rather than inclined travel, and are exploring ways to enhance friction between the pulley and cable for better grip. The project is expected to be completed in a week, with updates and pictures to follow.

Hey!

A couple of friends and I are building an electrical miniature cable car, kind of like this:

(attached below in case the code doesn't work)

We're mechanical engineering majors and love this kinda thing but we just started out and don't really know much yet, so we're just looking for new ideas as to how to go about doing this.

So how would you do it?

Motor Specs:
Looks kind of like this:

9V battery powered, small motor.
The only rule is to work with this exact motor.

We were thinking of using gears, but we're not sure how many, etc. so we would love to get your opinion!

Thanks in advance! It will be finished in about a week so we'll be posting pictures here when we're done!

Go Green!

If you know exactly which motor you want to use, it would be useful to share its specifications.

In addition, what is the mass of the cable car? Which angle does it have to climb? Did you measure values for friction and so on?
 
Thanks for your prompt response, mfb!

We are yet to find out all the specifications, the motor was merely given to us as is. All we know is that it is powered by a 9V battery.

As for the mass, the only requirement is that it has some sort of cabin, as long as it has that then it can be as light or heavy as we make it.

The cable seems to be pretty level, we won't know for sure until the day we test it, as the cable will be provided and set up by our school; But we're looking at fast, horizontal movement as opposed to escalated or inclined movement.

Friction is another thing we were thinking about.. we won't be able to measure anything that has to do with the cable but we were thinking of ways to increase the friction between the pulley and the cable so that it "grips" better. any suggestions?
 
Before I recognized the 9v battery in that pic, I thought your cart was 6 feet tall!
 
Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
TL;DR Summary: Heard in the news about using sonar to locate the sub Hello : After the sinking of the ship near the Greek shores , carrying of alot of people , there was another accident that include 5 tourists and a submarine visiting the titanic , which went missing Some technical notes captured my attention, that there us few sonar devices are hearing sounds repeated every 30 seconds , but they are not able to locate the source Is it possible that the sound waves are reflecting from...
