I am doing a science project which i have to measure the stress put on the models of 3 different kinds of bridge, and was wondering what the most efficient way to measure the force per square area.
Thanks.
I'm eventually going to have to build a bridge in Physics class, made of newspaper, for one of my labs. It's supposed to be a free-standing bridge that can hold a 3 or more kg load, while spanning a 1 meter gap. I'm allowed 10 sheets of newspaper and 1 meter of tape. Does anyone have any...
Hey, my physics teacher handed us this assigment and said have fun. He didn't explain what to do or go over how bridges work. So I was wondering if anyone here has done something similar to this. I believe I can work out the design, but what kind of pasta and glue would be most appropiate to get...
My first post... So be nice, or I'll blast you with a phaser... o:)
You are at one side of a canyon at the start of a bridge. The only way to cross the canyon is over the bridge. (no tricks to this, just a normal crossing of the bridge, don't try to walk on water here) On you side are 3...
How do i solve this? I wasn't given any examples at all. But I've tried to do this.
Iab + Iad = Ibc + Idc <--------- they have to or else Kirchoff's law violated.
so Vab = Vad but I'm not sure if Vbc = Vdc?
i'll continue assuming Vbc = Vdc
Vab/40 + Vad/20 = Vbc/70 + Vdc/50...
a women is walking at a rate of 6 ft/sec across a bridge 40 ft above the water, a man in a boat is immediately below the woman on the bridge , at right angles to the bridge and at the rate of 4 ft /sec. how fast is the man and woman seprating at the end of 10 seconds
what i have figured out...
Hi!
I'm currently doing a Fettucini Bridge project...
The material allowed:
20 Fettucini
1 meter of masking tape
Purpose:
to hold more then 3 kilograms
Please Help me~~~~
I need the replies by Thursdays.
Thanks to anyone who takes time to read this message.
Actual pictures are...
Hi everyone,
I've got to build a bridge from straws and pins for a year 12 physics class. Our bridges will be tested for strength by hanging weights off the bottom of them, and the strongest bridge wins. If the bridge collapses or the masses touch the ground, we fail.
Here's some more...
how do you build & design a bridge with these materials?
4 drinking straws
10 pieces dressmaker's oin
5 pieces of 5-peso coins (the bridge should be able to withstand the weight of these coins)
1 short bond paper
and a
1 meter sticky tape
Anyone who has performed this project...

Hey guys;
Is there currently any type of Wireless USB bridge thing?
What I mean.. I have a laptop, and when I use my digital camera I have to plug it in the back of my PC, which means I have to pull out the USB cable and bring it to my laptop, etc. Is there any way I can have the USB...
I am putting together a control circuit for a DC motor. This motor requires 110 volts DC. It must be variable speed.
I happen to have a nice continuously variable transformer box that goes smoothly from 0 to 130 volts. This should take care of the speed variations.
I hooked this up to a...
could some kind person please clarify a long standing argument within my circle of friends.It goes like this .There is a bridge spanning a gorge that can take a maximum of 80 kilograms(sorry for those not used to kilos ), a person wieghing 78 kilos must transport three gold bars weighing one...
Problem 11.
A hauing company needs to determine whether a large house trailer can be moved along a highway that passes under a bridge with an opening in the shape of a parabolic arch, 12m wide at the base and 6 m high in the center. If the trailer is 9m wide and 3.2 m tall(measured from the...
Hi guys, I'm new :smile:
Now, I came here in search of help to a homework problem I have. I've tried to solve for around 40 minutes now, and can't get past solving for k. Here's the problem.
The way I'm trying to solve is is by setting up two parts. One, I just solve for K in general...
We almost had a small disaster yesterday. Get this: Going by the book, using good numbers and a known technique for making such estimates, [I have played with this a lot] last night, in our creek that normally carries about 200 gallons per second in heavy flows, we had approximately 1800 gallons...
I've been dying for an excuse to try out the suit symbols in TeX, and I just had a fun bridge hand that is the perfect excuse!
Here's your hand:

\heartsuit: & \\
\spadesuit: & AKQxx

Well, I want to know what kind of games (preferably card games and board games) do you like to play. I specify the card game, bridge because people around me always give me the impression that if they love math, probably they also love playing bridge. Do you find people interested in math love...
lol, I hope that a donkey bridge is a used term in English? I'll explain it, just in case.. it is to make an associative link between things to be remembered.
Is there any easy way to learn the structures of all the 20 aminoacids and whether they are polar/nonpolar/charged?
It would be...
We have been doing a lot of work with wheatstone bridges in class lately and our teacher gave us a problem to try and I'm totally lost. The diagram that we were given has a 40 volt battery hooked to a wheatstone bridge circuit. The positive power flows into two resistors, one is 9 kiloohms and...
