you might be surprised to learn that engineers also use a version of them in earthquake-resistant buildings. Similar to their use in cars,shock absorbers reduce the shockwaves’ magnitude and help reduce pressure on the building.They accomplish this in two ways: vibrational control devices and pe...
Flapping wings produce lift and thrust in bio-inspired aerial robots, leading to quiet, safe and efficient flight. However, to extend their application scope, these robots must perch and land, a feat widely demonstrated by birds. Despite recent progress,
When possible, be sure to either point your x-ray beams down to the earth or up in the air: anywhere where it is unlikely to be intercepted by an animal or human. NEVER power up an x-ray tube in a shared residence or an apartment without full knowledge that the radiation will be co...
These measures reduce the effective range of the lidar system, but not the range of the driver's detector. With this extra time, a speeder might be able to slow down before the lidar gun can get a read on his or her speed. Speeders may also use a laser jammer. This works basically ...
νandYthe Poisson ratio and the Young’s modulus of the substrate andσthe average film stress. As sketched inFig. 1, the MOSS uses the deflection of laser beams to measure the change in curvature, and thus to monitorin situand in-plane the stress of the growing film10. In contrast, ...
be aware that the wool odor may be strong at first. The smell of wool is particularly noticeable in damp weather, so make sure to keep your mattress as dry as possible. For more information on how to reduce odor in your mattresses, see our section below on cleaning and caring for your...
We set the frames, braces, and beams up in four parallel rows running the 36-foot axis, according to the shoring plan. Drainage slope.We pitched the falsework to provide floor drainage toward the overhead door side by raising the opposite side 2 inches over the 24-foot-wide span. Not on...
and there is no local skin deflection since the skins are well supported by the webs.Bridge Project: North Bank BridgeLocation: BostonChallenge: Pedestrian bridge had to fit into a tight space amid other structures.Built in May 2012, the 690-foot long North Bank pedestrian bridge connects two...
beams and there is very minor deflection across lengths, despite 200+ kg loads with equipment on each section. I climbed on top of the bench many times to connect wiring at cabling at the equipment in the back of the bench and there was no any worry for rigidity. Each corner is fixture...
