Certain definitions become useless at certain points. Do we call Archeopteryx a bird or a reptile? When a new class of something can be identified, it is reasonable to create a new definition or new system of taxonomy.
There may come a time when we have replicating nanobots that will need to...
What FOR is the room rotating measured against? IOW, if the people inside the room feel a force pulling them against the wall, they could deduce it is rotating but in relation to what? Isn't the space it is rotating in an absolute frame?
Sometimes the antibiotic is chosen based on the target organ. Different antibiotics will reach different levels in various parts of the body. For example, if I am treating osteomyelitis, I want an drug that can reach bone tissue well. If I am treating a cystitis, I want one that will reach high...
You keep ignoring that we have a freewheeling hub. Tangential forces that create angular velocity of the wheel are also forcing it to spin around the hub. If I am holding the axle, I will not feel this force that you say is acting on the center mass because that force is also tangential to the...
Is a wheel with a freewheeling hub a rigid body? Doesn't the hub have it's own rolling resistance, different from the rolling resistance of the wheel on the ground? Once I overcome the rolling resistance of the lubricated bearings in the hub, the rolling resistance of the tire provides the...
I don't want to rehash our disagreement here, I would like others to step in and explain their thoughts on this.
Ksquared, You have already been told that the force was constant but then disagreed with spacecowboy immediately.
Your reasoning that the rolling force cannot be constant because...
I am in a disagreement with someone on another forum.
There is wheel with a freewheeling hub constrained to roll on a particular surface by applying force to the hub in the horizontal x direction. This person claims the tangential force applied to a wheel from the surface will also act on the...
