As shown below (Fig.1), A strain gage with gage factor of 2.02 is mounted on the bottom of a beam to measure the strain on the surface of the beam. The beam's Young's Modulus is 193 GPa. A wheatstone bridge circuit was constructed as sketched in Fig. 2. Al resistors including the gage itself is 1202. Supply voltage is 5.0 V DC. The bridge is initially balanced when there is no load (a). when a downward load is added, will...

1. The cantilever beam shown in the following figure is subjected to a load P or a deflection o at its free end. Two gages A and B are mounted at locations A and B on the top and bottom faces of the beam. Gage A is used to measure strain in the y direction (Ey), and gage B is used to measure strain in the x direction (Ex). Assume that: E=30(10) psi, Poisson's ratio v=0.3 a) Determine the theoretical...

Cantilever Testing Procedure 1. Check dimensions of the bar stock aluminum. You should record the width and thickness with a caliper and then use the yardstick to measure the length of the bar to the table. Also record the distances to each of the sets of gages and the distance to the middle weight. The distances are fairly accurate so it is safe to round to the nearest whole inch, except for the distance from the free end of the...
