The displacement vector is \(\vec D=\overrightarrow {PQ}=\left\langle2,5,2\right\rangle\), so by Equation 12, the work done is\(\begin{split}\vec W&=\vec F\cdot \vec D=\left\langle3,4,5\right\rangle\cdot \left\langle2,5,2\right\rangle\\&=6+20+10=36\end{spl...

Method for displacing a moving body (4) in which a force (F) is determined, which when applied to the body ensures that it will move the exact distance intended within the intended time and in addition the elements (MA1-MA3, 4) caused to move by the displacement of the body will be ...
When stress is applied to a stationary object, the resulting deformation or displacement of its material causes strain that is captured by the strain gauge. Load cells and force sensors are designed to focus the stress (tension, compression, pressure, load) through elements where the strain gauges...
