Loading the beam in this way, rather than loading the beam at just one point, has two main advantages: (i) it allows a strain gauge to be placed at the top of the beam and (ii) the constant bending moment area that it creates gives better strain gauge performance when stretched or compressed. 6.4mm W/2 8mm a 38.1mm W/2 indicates strain gauge 38.1mm Figure 2 the dimensions of the cross section of the beam and the position of the strain gaugesarrow_forward2.
