Hello everyone. I'm trying to figure this out, The problem says: Suppose that the Tower of Hanoi problem has four poles in a row instead of three. Disk an be transfeered one by one from one pole to any other pole, but at no time may a larger disk be placed on top of a smaller disk. Let S_n...

Hi, I just popped into see if there are any budding young engineers here (hope I got the right forum) interested in helping with a problem that I have been nutting out over the years... Hope your forum can help. It is all about controlling sway and buckling of members and gaining the full...

I've spent about 6 horus this weekend trying to construct to build a paper tower that will support thick textbook 14 inches off the ground. the requirement is that it weigh less than 15 g. you can use tape and paper and that's it. Cylinders cannot exceed 5 cm in diameter. Tried making a bunch...

Given the tower is 70 m high, and the force of FAB= 2 kN and the x and z components of the vector sum of the forces exerted on the tower by the 3 cables are zero. I have found the lengths of all 3 cables. I have also found the unit vectors for all 3 cables. I just do not know how to find the...

Consider an exponential tower of three thousand 7's. What is the remainder when you divide the tower by 11? Note that this notation means 7^(7^7) not (7^7)^7. So it's kinda like the Ackermann Function maybe? The final answer must be given as a single integer in the range 0-10. Anyone got...

Crazy Power Tower Problem. Consider an exponential tower of three thousand 7's. What is the remainder when you divide the tower by 11? Note that this notation means 7^(7^7) not (7^7)^7. The final answer must be given as a single integer in the range 0-10. Anyone who can help?

i'm stuck on a problem. Let's say you have a large water tower. and the pressure is basically static pressure from the weight of the water. But when the water starts moving through pipes is the pressure then dynamic pressure? In which would you have to calculate the pressure from 1/2 density of...

I was just wondering if anyone could explain the phenomenon seen when a water droplet falls into larger expanse of water (i.e. the kind of water 'tower', like in the picture)? It's something I've wondered about for a while, and I've never managed to come up with a satisfactory answer myself...

I am attempting to design my own Parabolic photovoltaic solar tower for a school project. I am working on numbers at the moment, but any helpful Ideas about mirror angles or Pv collector chip placement would really be great. Also I plan on using a shaped Non-Imaging Fresnel lens to help...

Can anyone help with this problem?? Children bring their old pumpkins to a tower and compete for an accuracy in hitting a target on the ground. Suppose the tower height is h=8.0m and the bull's eye on the ground is a distance d=3.4 m from the launch point. (neglect air resistance.) If the...

Hi dudes, don't be put off by the clumsy notation here. I was wondering about these particular exponent towers and this curious property of theirs... Let p be a positive integer. Then the exponent tower, composed of p+1 parts each of value p^(1/p), equals p. e.g. for p=2. tower part...

How Does One Find The Differentials Of Power Functions. Examples Like A[x]^b[x]^c[x]^d[x]... Where Those Are Functions Of X? In Cases Where These Functions Are Power Towers Of Another Variable,what Happens?

ok the question goes sth like this,an equation of p=c1+c2*r^0.625cos@,where p is the pressure exerted on the soil,c1 & c2 are constant to be determined,r& @ are polar coordinates.(@ measured fr the x-axis which is of direction south) now the question states that pisa lean at an angle of...

The Stupid Quetions thread. No one knows how to play anymore and I hate to see the once magnificent Tower of Babel that it was whimpering and quivering like a stupified woodchuck hit by a car. Discuss.

I was out stargazing tonight in the middle of nowhere. Theres plenty of washes out in the skirts of our suburb and I drove out into one of them to avoid city lights. After about ten minutes I started noticing a small clicking sound, kind of like that of static electricity or a small spark, and...

Giant Paper Tower :) Fun Hello, My physic's class has been kicking butt all year, so much in fact that we are done with the book early. My teacher is having a contest for us. Build the tallest paper tower we can... ONLY using paper, but as much paper as we want. Construction MUST take place...

hello. i have to build a "quake tower" for my high school physics class. it must be made from bolsa wood and be able to hold something like 10 pounds and be put on a vibrating table and not collapse. has anyone ever done a project like this before? do you recommend any specific designs? any...

hi there, first post, hopefully not many more to come, i can usually do these problems but I am swamped, but then so is everyone else, just can't think about this stuff... You are in an elevator at the top of the CN tower. You have a pendulum and allow it to oscillate. The elevator falls to...

There is a famous problem called the tower of hanoi in which you have n disks of increasing diameter, and three pegs. The object is to move them from one peg to another in such a way that no larger disk is on top of a smaller disk. the number of moves is defined by T(n)=2^{n}-1 A far...

Tower on Mars?? Help me debunk.. Theres a website pointing out something strange taken by the Orbiter. It's a picture with what appears to be an extremely tall TOWER on the surface of Mars.. http://www.geocities.com/marsunearthed/tower/tower.html I started wondering well is the picture at...

I'm not sure if this would go more into the engineering section, but I think physics concepts would help out more. I might be wrong, if so, please move this thread. We have an extra day in Physics Lab and we're going to do a one-period long project -- We're going to be given a base, a normal...

Question: A man is looking at the top of a tower. The angle of elevation to the top of the tower is 10 degrees. 100m closer to the tower, a man has an angle of elevation to the top of the tower of 20 degrees, how tall is the tower? My Problem: I can solve this ver easily by recognizing...

Three survey stations X, Y, Z lie in one straight line on the same straight plane. A series of angles of elevation are taken to the top of a chimney which lies to one side of XYZ. The angles of elevation of the top of the chimney measured ay X, Y, Z are 14 degrees 02 ', 26 degrees 34' and 18...

Looks like it is getting closer to being built.

Rather than dig up the old one, thought I'd just start a new thread. For those of you Stephen King fans out there, the next installment of the Dark Tower series is due to be released this month. I've been reading King's books for close to 20 years, so I'm of course a die hard fan. All I can...

Stephen King's grand epic(and his career, rumor has it) is drawing to a close. The final three books in The Dark Tower Series will be released within the next 18 months. Is anyone as excited as I am??
