Moving across the beam again, we come to another force; a positive 10kN reaction at support B. Again, add this +10kN to the shear force diagram (which is currently at -10kN) which will bring us to a shear force of 0. Since we are at the end of the beam, we will go no further ...
After simplifying as based on beams load, and then according to the general calculation of internal forces of continuous beam. (2) the existing view of column foundation beam can be regarded as the calculation of elastic foundation beam. The counterforce of the pile top is acted as the ...
We developed a dynamic model of the system to calculate the parameters shown in Fig. 2F that minimize the damage upon impact during the perching maneuver, described in Supplementary Method 2 and 4. The dynamic model estimates the motion of the system and the stresses in the joints for a give...
Televisionis certainly one of the most influential forces of our time. Through the device called a television set or TV, you are able to receive news, sports, entertainment, information and commercials. The average American spends between two and five hours a day glued to "the tube"! Have y...
It takes a much more powerful electron microscope—using beams of electrons instead of rays of light—to take us down to nano-dimensions. Let's take a closer look at electron microscopes and how they work!Photo: This Hitachi S-4700 field-emission, scanning electron microscope can magnify over...

Two back-to-back beams extending outward from a pier can balance one another—just as a tightrope walker can balance by holding both arms straight out from her body. That's the basic idea behind the cantilever bridge. Normally, when we talk about a cantilever, we mean a beam supported at...
If you want to start small, for example, from about 40,000 m2 of a limited range of precast floor slabs, piles and beams annually, you can have a basic installation of the mechanized set of four hollow core slab production lines in an open-air site on simple foundations. The line needs...
I got on the road a little later than planned – this was the day after changing the clocks back to standard time and I wanted to have plenty of daylight left. At the first stop, everything went smoothly. I put up my 31ft Jackite mast with the 30.5ft random wire going to a 9:1...
Rotation generates shear forces between the flanges, which is captured by the foil strain gauges bonded to the sensor beams and transduced into electrical current by the Wheatstone bridge. How to measure stall torque of a dc motor? For a given application, i.e. motor torque measurement, a ...
