    Undergrad Force Needed to Push a Manual Treadmill

    I shall build it then over Winter break, after this semester of college and post pictures to this thread and let you know if it works!

    Undergrad Force Needed to Push a Manual Treadmill

    No break needed on these manual treadmills:

    Undergrad Force Needed to Push a Manual Treadmill

    The breaking is needed on that particular treadmill because it is designed to be more difficult for athletes not because a breaking system is inherently needed.

    Undergrad Force Needed to Push a Manual Treadmill

    The picture of the manual treadmill I posted earlier has a magnetic breaking system to make it more difficult for the athletes because it is designed for speed work not because a break is inherently necessary as evidenced by these manual treadmills which do not have breaking systems. Which...

    Undergrad Force Needed to Push a Manual Treadmill

    The market /does/ have many treadmills based on my idea (its not my idea just a re-imagining of the concept) - I came here because in my plans to build one by myself based on the ones I saw out in the market I needed to know how much force moving 100lbs along many small bearings would take...

    Undergrad Force Needed to Push a Manual Treadmill

    I do agree that tread width should be smaller and I have halved the width of the treads in my design document, they are now half of the width than in the picture in my post. I disagree that walking on this treadmill would make it hard not to fall down a lot - each step is moving 100 lbs...

    Undergrad Force Needed to Push a Manual Treadmill

    The reaction force is having to move the 100 lbs that the treads weighs. When I said manual treadmills exist I wasn't talking about animals - manual treadmills for humans exist is what I meant. And one very similar to mine in design:

    Undergrad Force Needed to Push a Manual Treadmill

    These kinds of manual treadmills do exist for dogs, they're called slatmills and either dog nor human slip quite /that/ dramatically so I think you're overestimating the lack of friction a bit too much. The reason I need to knwo how hard it would be to push the slats along is because my version...

    Undergrad Force Needed to Push a Manual Treadmill

    I apologize if this is in the wrong thread, I'm new. I need to figure out how hard it would be for Jim to move the treadmill treads along its track of bearings. This isn't for homework, it's just something I want to know. Jim weighs 160 lbs. The rope isn't holding him up, it's there for him to...

    Undergrad Solving Treadmill Friction Problem for VR Build

    Dude, look at the picture in the post, the rollers inside the round track roll on the rollers underneath and around it.

    The top view is a circular closed tread surrounded by rollers. The inside along the edge has rollers too.

    How would I downsize the weight of a running person?

    Undergrad Solving Treadmill Friction Problem for VR Build

    Ten of those rollers for the design cost 20 dollars, it's going to cost at least 400.0 dollars to build this thing. I can't just build it before knowing if it'll work or not.

    Undergrad Solving Treadmill Friction Problem for VR Build

    @rumborak the tread has to be flexible, but not stretchy or elastic at all.

    Undergrad Solving Treadmill Friction Problem for VR Build

    @rumborak the picture in my post is a side-view, everything is actually circular, allowing the tread to rotate in any direction around the rollers that encircle it in the way shown.
