i need some help. i am supposed to design a vehicle that is powered only by one standard rubber band to transport an egg to the greatest possible horizontal displacement without breaking the egg. the vehicle can't have any rotating parts. must be constructed from basic parts (ie not...

im to design something, a plane, or any kind of material to let it stay from the time of release up to it falling into the ground for 13 seconds provided that it is powered by a rubber band... i'm having a hard time thinking about it, having it stay in mid-air longer than usual, and just want...

If you have a rubber band wrapped around a cylinder, how can you tell the tension in the band? What parameters do you need to know?

I need to prove that the distance of an object launched by a rubber band decreases as its mass increases, algebratically. Can anyone help me? Thanks.

Here's a cute problem I came across recently. Suppose you have a rubber band with spring constant k, mass m and unstretched radius r. Now suppose you have a frictionless cone and the angle of the peak is 2 \theta (that is, if you project the shape of the cone onto a plane it looks like a...

Imagine that now i have a can. I poke a hole at the centers of both the bottom and the cover of the can. Then i tie a rubber band onto the holes that it goes across the tin from the hole at the bottom to the hole on the cover. After that i stick some plasticine onto the rubber band. When i roll...

Hi all. I have something of a problem in my understanding of a current lab experiment that I am doing in my second year. The experiment is set such that we explore the elastic properties of an elastic band through small and large deformations and measure the force that it exerts on the...

Set-up: Rubber band modeled as an Ideal chain (polymer) with Nr (links) monomers pointing right, and Nl monomers pointing left each of length l. Find expressions for the length of the band, its statistical weight (iI think that means the multiplicity?) and its entropy, in terms of N[SIZE="1"]r...

Hello everyone My phisicsproject for school is to test the strength in every rubber band in a bag with new fresh rubberbands. The problem is i can't really understand how I should do this test, and i hop you guys can help me out. //daniel :confused: <-- me right now :-p

This has caused me to be very confused because at one time i did an experiment, the rubber band followed Hooke's Law, but at another time, it does not. When I search the internet, some websites state that such experiments are only correctly done when the force is linear with the extension...

OK, maybe this is an odd question, but here goes: When I pull on a rubber band, is the force I "feel" the resistance to co-valent bond separation? Am I actually "feeling" electron forces?

I need help. I need to design a device to transport a 1kg pass ten meters over a level surface using the energy stored in a #10 rubber band. I decided to use three wheels at the structure, and i created a car with a basswood top and the rubber band is wounded up at the rear axel to get power...

A Rubber Band?? OK...i need your help people... i have to construct a vehical that can transport a 1 Kg weight over 10 meters using any materials i please...here's the catch: Its only source of power can be a size-10 rubber band! It can have no other source of power and it cannot be launched...
