Shear Stress In Beams


shear stress in beams
    shear stress
  • A shear stress, denoted (tau), is defined as a stress which is applied parallel or tangential to a face of a material, as opposed to a normal stress which is applied perpendicularly.
  • A tangential force divided by the area (FORCE/AREA) on which it is applied. The shear stress is equal to the viscosity multiplied by the shear rate (measured in units of pressure, i.e., MPa or psi). At the die lips under usual production conditions, the shear stress may reach values of 0.
  • Stress acting parallel to an imaginary plane cut through an object.
    beams
  • (of a light or light source) Shine brightly
  • radio beam: a signal transmitted along a narrow path; guides airplane pilots in darkness or bad weather
  • (beam) smile radiantly; express joy through one's facial expression
  • (beam) long thick piece of wood or metal or concrete, etc., used in construction
  • Transmit (a radio signal or broadcast) in a specified direction
  • (in science fiction) Transport someone instantaneously to another place, esp. to or from a spaceship

HDR Broken Bridge
HDR Broken Bridge
This is a battered remnant of the bridge on Iceland's Ring Road that, until 1996, spanned a nearby river. That year, volcanic activity under the Vatnajokull icecap melted enough of the icecap's underbelly that it overcame the ice's ability to hold it back. The glacier broke open and released 50,000 cubic meters of water per second, bringing along with it boulders and icebergs which impacted the bridge and destroyed it. Even with the picnic table to aid in scale comparison, I was unprepared for the sight in real life. I recognized the site perhaps a mile away, and my reaction upon pulling into the parking lot was something along the lines of "holy crap, it's #@&*ing HUGE!" Were it not for the small rock barrier underneath it, I could have easily driven my car under the beams. This is an HDR composite of two images, combined in Adobe Photoshop CS3.
