Synopsis: Physics & astronomy: Physics: Physical mechanics:

Allows mechanical devices such as tractors to warn mechanics that a failure is likely to occur soon.

Sexologists study everything from puberty to sexual orientation to the mechanics of sexual intercourse. They also study sexual dysfunctions.

Building in tornado country Even in Tornado Alley buildings are designed to withstand only 90 mph (145 km h) straight-line winds said Partha Sarkar who studies wind engineering and aerodynamics at Iowa State university.

#Honeycombs'Surprising Secret Revealed The perfect hexagonal shape of honeycomb cells once thought to be an incredible feat of math-savvy insects has now been explained by simple mechanics.

and explored the mechanics of two plausible scenarios: One in which the bees focus their heat only at points where neighboring cells touch (a total of six points per cell) and another in

Teams must address aerodynamics to score well in the design event but may use whatever type

But researchers who eavesdrop on plant hydraulics are discovering that certain species like pine trees and Douglas firs can repair the damage on a daily

I think plant hydraulics will be the piece of the puzzle that tells us which species are going to live

Plant hydraulics will tell us what our future forests will look like in 50 years. Two geologists in Arizona are also building a low-cost acoustic detector crowd-funded at about $1000 drawn by the age-old allure of communicating with plants.

'The phrase the birds and the bees is a metaphor for explaining the mechanics of reproduction to younger children relying on imagery of bees pollinating

But besides the plane's engine and weight the pilots and the engineers and mechanics who work for them are free to experiment with their planes'designs Mangold said.

so that the body's center of gravity balances on top of its legs. Their thin legs give them great speed and maneuverability too.

whether bumblebees vertical range was limited by aerodynamics and physiology. Working in the mountains of Sichuan, China,

Sorry your understanding of orbital mechanics is flawed fundamentally. As DCRANNE correctly mentioned Earth would neither be accelerated nor de-accelerated (who or

and speed (aka angular momentum) in relation to the only center of gravity the still have -which is earth. So all lower earth orbits would basically be undisturbed completely.

Classical mechanics assumes physical interactions propagate at infinite speed. In general relativity which supersedes classic mechanics gravity travels in waves at the speed of light.

The speed of gravity has actually been measured experimentally not with pinpoint accuracy but within the ballpark of the speed of light.

and teach classical mechanics because it is a good approximation of how objects with low mass and speed behave

Coke is strong enough that mechanics use it to kill battery acid. It also contains phosphoric acid the same chemical used to kill rust.

or disprove the actual mechanics or benefit to these practices. Kind of disappointed in this one popsci.

War has spawned not only weaponry but a knowledge of mechanics in all directions. General Hap Arnold once remarked that without war we would probably never have developed the airplane

which keeps our inventiveness in the mechanics of destructiveness alive. This too may be the result of our uneasiness in the face of our exploding numbers.

But until recently inventors lacked the aerodynamics expertise to turn diagrams into mechanical versions of something as quotidian as a fly or a bee.

Although insects and their relatives represent roughly 80 percent of the world s animal species ome 900000 known types he mechanics of their flight had long been an enigma.

And the stubby wings of bees and other insects lift far more weight than can be explained using conventional steady-state aerodynamics principles.

Working independently the researchers characterized the aerodynamics of flight with unprecedented specificity. Dickinson and electrical engineer Ron Fearing won a $2. 5-million DARPA grant in 1998 to apply these principles to a fly-size robot.

which aerodynamics insights the students should try to reproduce. Flies have really complex wing trajectories.

The Techject Dragonfly takes advantage of an aerodynamics principle called resonance. When wings flap at their most efficient frequency hich happens

But within milliseconds the fly s center of gravity appeared to pull the fly back into a stable position.

or fluid flow in hydraulics. Reducing edge connectivity's edgehowever while a great deal of research has been carried out in mathematics to solve problems associated with edge connectivity there has been relatively little success in answering questions about vertex connectivity.

What we learn from them can teach us more about human muscle mechanics to potentially improve physical therapy treatments

The results shed light on more than the mechanics of moth flight--it may redefine our understanding of how our own muscles function.

A key challenge concerns the mechanics of securing the participation of farmers in delivering land-use changes to benefit society A recommendation that the research team puts forward involves the reform of the European union's (EU's) Common Agricultural Policy (CAP.

but do not yet stop them as effectively as real leaves Loudon said suggesting that crucial mechanics of the trichomes still need to be determined.

It's one of the pillars of large-scale material mechanics he said. For graphene we call this a pseudo Hall-Petch

Co-authors of the paper are graduate student Zhigong Song and his adviser Zhiping Xu an associate professor of engineering mechanics at Tsinghua.

Bucinell's particular expertise is in experimental mechanics and the mechanics of reinforced materials and is tasked with seeing how strong sample material is under different parameters.

This includes determining whether mycelia bind better to one plant material or another; and does the way it's treated--with heat

Within 25 years practically no ash trees may remain on either side of the St lawrence Seaway said Akhlesh Lakhtakia Charles Godfrey Binder Professor of Engineering science and Mechanics at Penn State.

Specifically we coated a dead female beetle with a vapor of nickel and used the'nickelized'shell to fabricate two matching molds in the shape of a resting beetle said Akhlesh Lakhtakia Charles Godfrey Binder professor of engineering science and mechanics

and hydraulics should both increase in drier areas. But Givnish and his team wanted to know the importance of each constraint.

which hydraulics retards photosynthesis. The isotopic composition should also remain stable if resource allocation alone sets maximum height because resource allocation does not directly affect the stomata.

but also makes it less ductile--meaning it can't be stretched very far without breaking says Xiaolei Wu a professor of materials science at the Chinese Academy of Sciences'Institute of Mechanics

It's very rare in fluid mechanics to discover a new phenomenon like this Peacock says.

Consideration of disclinations should provide scientists with a new tool to explain many phenomena related to the mechanics of solids.

On 25 of its larger semi delivery trucks, Oakhurst will install side panels that are supposed to improve aerodynamics and,

Logan Ward reports for Popular Mechanics: On September 28, 2010, the Federal Aviation Administration issued a Light Sport Aircraft certificate for the Maverick Sport,

and one essay penned for Popular Mechanics magazine in March 1932 dealt with predictions of
