What is Bend: Definition and 140 Discussions

Bend is a city in and the county seat of Deschutes County, Oregon, United States. It is the principal city of the Bend Metropolitan Statistical Area. Bend is Central Oregon's largest city and, despite its modest size, is the de facto metropolis of the region, owing to the low population density of that area. Bend recorded a population of 76,693 at the time of the 2010 U.S. Census, up from 52,029 at the 2000 census. The estimated population of the city as of 2019 was 100,421. The Bend metro population was estimated at 197,488 as of July 16, 2019. It is the fifth largest metropolitan area in Oregon.
Bend is located on the eastern edge of the Cascade Range along the Deschutes River. There the Ponderosa pine forest transitions into the high desert, characterized by arid land, junipers, sagebrush, and bitterbrush. Originally a crossing point on the river, settlement began in the early 1900s. Bend was incorporated as a city in 1905. Economically, it started as a logging town but is now identified as a gateway for many outdoor sports, including mountain biking, fishing, hiking, camping, rock climbing, white-water rafting, skiing, paragliding, and golf.

    Negotiating a Bend: What is the Role of Inertia?

    Hi there! When I had first learned about the situation of a vehicle taking a turn around a bend, I was quick to conclude that the vehicle would bend inwards (towards the center of the circular path) as I had the image of the MotoGP racers who bend to the extremes to negotiate sharp bends. But...

    Shear stress on a bar with a bend

    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...

    Max Von Mises Stress Calculation for Pipe Bend

    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.

    Energy required to bend an elastic rod

    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...

    Why does viscosity help air bend?

    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...

    What is the impact of a 90 degree bend on flow in an engine's oil gallery?

    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...

    Does Light Bend Spacetime and Have a Gravitational Pull?

    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.

    Why do spokes bend differently when heated?

    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...

    Does Gravity Bend Light or Curve Space-Time?

    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...

    Optical Fibers-Min. Bend Radius
