(Two identical sets of graphs for affixing strain gages to the specimen by each design)
You are asked to come up with two different designs in order to sense the bending
strain only. In each design, you are allowed to use only two strain gages.
In each design, you need to do the following:
i) Showing on the graph how the strain gages are affixed to the specimen;
ii) Writing down the expressions of measured strains by each
iii) Illustrating how the gages shall be connected to a bridge circuit;
iv) Presenting the output expression3;
v) Calculating the bridge constant;
vi) Drawing conclusions on which design is more preferable.
