1. Four identical strain gages are mounted in the constant-moment region of a beam as shown in the figure below; two are axial (gages 1, 2) and two are transverse (gages 3, 4). These are placed in a Wheatstone bridge (see figure from Table 11.1 for labels) and the bridge constant is given below (see course slides). The bridge is balanced with no loads applied and then generates a bridge output of 24.970 mV with the loads shown below applied. Determine the gage factor for the gages using the following information: E = 16.5106 psi, v=vp=0. 34, E-8 volts, and gage resistance at balance is 350 2. Also, determine the resistance (in 2) for each of the gages when loaded.

I already have a gage factor of 2.08. Need R1, R2, R3, R4. Please show how?

Step by Step Solution

There are 3 Steps involved in it

Step: 1

Since you already have the gage factor GF you can calculate the resistances of each strain gage when ... blur-text-image
