Bend Definition and 139 Threads

Homework Statement I have encountered this problem several times in class, but have never really understood it. There is a solid round bar that is fixed on one end, and that bends 90 degrees a ways down. At the free end of the bar there are forces applied in each Cartesian direction. Like...

Homework Statement A car goes around a curved stretch of flat roadway of radius 112m. The magnitudes of the horizontal and vertical components of force the car exerts on a securely seated passenger are, respectively, x= 220N and Y= 530N. a) At what speed is the car travelling? b) This...

Hi, I'm trying to calculate the max (von Mises) stress in a 90o pipe bend. Now I know (I think) how to do it for a straight pipe, but can anyone point me in the right direction as to where I can find this analysis for a pipe bend? Thanks in advance.

what suitable electric motor for create bending pipe machine?. could you give me the idea how to create the machine and easier for the user to use for bending pipe line?

Hi All, I know that when water pass through a 90 degree bend pipe, there will be a pressure lose. However, how to calculate the energy/potential loss for electrical current pass through a 90 degree bend wire/resistor. Academic paper appreciated! THanks

Thinking in terms of the conservation of energy, it seems to make sense that if you took a relatively elastic rod with hooks on either end, so that it could be bent all the way around and made to hook to itself (and make a loop), that the energy required to bend it into a closed loop would be...

Hi guys, simple question I have: Do particles without a rest mass (including EM radiation) cause spacetime to bend? Or only those with a rest mass have gravity?

Can gravitons bend space-time? How can it be shown experimentally? Ideas?

Hello all, I'm trying to nail down why the viscosity of air helps it bend around a curve. I have a specific, simplified example in mind to cut away other phenomena. Imagine the region immediately behind the camber of the top of a typical airfoil. That is, the place where the slope of the...

I'm not a student. I'm a 64 year old guy trying to determine the flow change (volume) in an V-8 engine oil gallery. The feeding gallery comes directly from the oil pump and is 7/16 inch. It ends at a 90 degree intersection with a 3/8 inch gallery. I understand the loss of volume due to the...

I have a centrifugal pump that gives flow of 56 lit/min at 50 psi. Media: clear water, Temp. ambt The discharge pipe size: 1 1/2", Material: SS Total pipe length: 14 feet At 3 feet from pump discharge there is 90 degree bend and again at 6feet there is 90 degree bend. My question is what...

When two magnets are taped together with both north sides touching does the magnetic flux stay in its normal possition or does it bend, if it does in what way does it bend?

how can it be that gravity can bend time and slow it down, how can gravity influence a dimension of space?

I've looked (googled) but can't find any info on this experiment other than the apparent AP news release that is duplicated on several websites. If this is a real experiment in a lab somewhere, anyone know where to find info on it? I realize this story is just barely accurate fodder for the...

will light bend when it reach in front of a black hole?

E=mc^2. Mass warps spacetime. From use of the aforementioned equation, light can have a hypothetical mass (can't it?). So, does light bend spacetime, and consequently, bend light? Does light have a gravitational pull is another way of phrasing my question.

I'm fascinated by radiation as I have been learning a tidy bit about it. I have learned that radiation can be bent by refraction and have heard some idea that it can be bent by gravity ie a black hole. What other things bend electromagnetic radiation? Does electromagnetic radiation get bent...

I have an idea why, but would like to know if there are any official 'theories' ? also, I can think of an idea of why the speed of light is 300k kilometers in vacuo, but is there an 'officially' accepted theory? I havn't found any in the literature. thanks Talon D.

Can someone tell me how much does a light ray bend when it passes over the surface of the densest star known? Is it like 1 degree, or more like 30 degrees? Please leave out black holes, this question is about normal stars, the densest one that is known. Is Sirius the densest normal star...

Hi. Could anyone here help/teach me how to calculate the resulting bend in space-time from any particular mass? Specifically I'm trying to figure out how much space-time is stretched or bent relative to "unbent" space-time in space. I'm not exactly sure this is the right question to be asking...

Homework Statement Car mass m drives round a bend in a circular arc radius 44m with the road banked at an angle \alpha where tan\alpha=3/4. The coefficient of friction \mu=0.6 of the car with the road. What is the maximum velocity the car can travel at without sliding up the banked...

I am asking this question on behalf of a forummer from Gendou.com's Physics Board... Sorry if a similar question has been posted before... ------------------------------------------------------------------------------------ Here is a mechanics question which totally stumped me: A car...

Hi, Firstly i don't really know anything about fluid dynamics so go easy on me :shy: In simple terms how does air flow through a 90 degree bend? ie where is it moving faster? I initially thought it would be along the outside wall as it has further to travel. If it makes and odds it's an...

Corrective lenses and contact lenses work because of refraction. Do they bend light in a special way that will correct a person's vision for whatever reason it is?

Cheap (or very old) bicycle spokes are made of carbon steel. Most modern high-quality spokes are made of stainless steel. When bent at roughly 90 degrees and heated with a propane torch, a carbon spoke bends further, curling up slightly, but a stainless steel spoke unbends, uncurling...

I have question that I'm sure has been asked before. Maybe if you could point me to a thread that'd be great. The water flows steady discharging to atmosphere. I need to find the horizontal componant of force in the flanged joint & find if it's in tension or compression. I think I have a...

Looking for help interpreting a proof of G.R. please. . . One of the earliest proofs of G.R. was the deflection of light by a gravitational field, first shown in 1919 during a solar eclipse. I think Einstein predicted approximately 1.7 seconds of arc deflection during that eclipse. But...

Waves bend when they pass throungh a narrow gap.It is the definition of diffraction. what is the reason that when the water waves pass through a narrow gap in ripple tank the wavefronts become circular? what is the reason that when the water waves pass through a wide slit in ripple tank the...

yes i know the basics of how it curves (bends) in mid air, BUT, why does it bend when there is little to relatively no spin on it? i have noticed this a few times.PS: if you want to catch the craziest bend, here it is... [PLAIN]&search=roberto%20carlos[/URL] EDIT: sorry i picked the wrong...

Does gravity bend light by pulling at the photons or does gravity curve the space-time the light travels through, making it appear that the light is bend? I thought it was the latter but I wasn't able to confirm it. I also run into a problem with black holes. A black hole must curve...

Questions arise in my high school physics class about all sorts of things. A current thought question had to do with a piece of paper in space and a constant force being supplied at its center, perhaps by an alien or astronauts finger tip. Would the outer edges of the paper bend from the center...

I remember reading somewhere that there was once a man who could bend spoons & forks by just gazing at them using his so called 'mind power'.. Can this be done?? I actually believe that there are so many hidden powers in the human brain that we can't even think of..brain waves is one...

The smallest outside radius, R, permitted for a bend in an optical fiber if no light is to escape is called the minimum bend radius. I know that it is proportional to the fiber's diameter, but I don't understand why. Any thoughts?

I have recently heard a rumor that a hollow pipe can endure a greater load without bending than a solid rod. Is that true, and why? Thanks.

Consider a situation where a friend have a red laser or a torchlight shining across the room. And you are standing at the side, perpendicular to the light beam. If light traverse in a straight line, why is that you can see the light shining across the room when you know that the light that comes...

Black holes are currently thought to just be big things (lack of better word) of gravity that pull stuff in. If gravity relies on mass and light has no mass, how is light pulled into black holes?

I've heard that a property of waves (water/sound/light...) is that they can bend or refract around an object as long as the sides of the object are shorter than the wavelength. I'm trying to picture what would cause this 'bending', but its not coming to me. Can anyone help to explain how the...

By how much, if at all, is a ray of light bent when it passes by the sun a million miles from center? The bottom line is, do you have an order-of-magnitude feel for the sun's gravity? Can you judge the rough size of the bending angle well enough to spot it in the line-up? In natural units...
