Will a rubber band or a string hold more weight without breaking?
I would think a rubber band would snap and a string would hold without breaking
Is a rubber band a string?
no
What did the rubber band replace when it was first made?
String.
How can you change how fast a string or rubber band vibrates?
strike it softer!
Weight of 1?
#32 rubber band?
Is using a rubber band instead of a string on a mousetrap car better?
Yes
How long is a piece of string if you cut it with 6 scissors to cut it and you have no rubber band?
|<-------------------------------->| (not to scale)
How do you make a homemade string instrument?
A stretched rubber band between two fingers.
What is a rubber band's weight?
The weight depends on the volume, or size, and the density of the band. In the same way, a book's weight depends on its volume and density.
How does the yo-yo work?
It's kind of like a rubber band, except your hand is the rubber and the string is the band. The momentum of the yoyo going down and you snapping your wrist makes it go back up.
What is the ultimate tensile stress of a rubber band?
You must hang weights from a rubberband until it snaps;then divide the total weight by twice the cross-sectional area of the rubber band. ThisÊwill be the Êtensile load of the rubber band.
How long does it take for heat to expand the length a rubber band stretches?
A relaxed rubber band seems like it should expand when heated but in fact it will contract due to the increase in the tension of the rubber band. The force of tension in a rubber band can be modeled by Hooke's Law:F = -kxwhere k the spring constant is directly proportional to the temperature. According to Hooke's law a stretched rubber band should have an increase in tension when heated. However a stretched rubber band cannot contract until its let go and by Hooke's law there is no tension on a relaxed spring so how can there can be any contraction? Well, tension is derived from the change in Entropy by heating the rubber band. Entropy is a way of measuring the amount of 'disorder' in a system. The rubber band can be looked as a string of molecules. So when the string is all laid out it is has low 'disorder'. If the string is all balled up it has high 'disorder'. So if rubber band is heated the Entropy increases which pulls the string of molecules into a ball. This increase the tension in a relaxed rubber band which causes it to contracts it.
