AI Thread Summary
The discussion focuses on finding beginner-friendly books about elastics, specifically for building a rubber band-powered cart. Participants clarify the definition of "elastic," primarily referring to rubber bands, and explore the differences between elastics and springs. The project aims to prioritize distance and lightweight design for optimal performance. Questions arise regarding the mechanics of energy storage in elastics versus springs. Overall, the conversation emphasizes the need for resources that can guide the construction of an effective rubber band-powered cart.

Are there any good books on elastics for a beginner? I want to build a cart where I use only elastics and wood to propel the cart...What books can help me with this?

what is an elastic?

in what sense is a steel spring not an elastic?

if a cart is driven by a twisted rubber band (like a rubberband
propellerdriven airplane) is the rubber band acting as a spring
or as an elastic

or both?

I suppose that spring materials can store energy without changing length very much---by torsion and bending

and I suppose elastics store energy by changing length

But I am just guessing. Is there an official definition
of what an elastic is? sorry I can't help. Just curious.
 
what i meant by elastic was rubber band

I understand, thanks. So your project is to make a rubberband
powered cart.

What performance category is most important to you?
speed? distance (range) on the level? hill-climbing ability?
load-bearing?
 
Its distance and lightweight
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
