A cantilever beam has stress created by a downward point load F. The beam is instrumented with 4 strain gauges arranged in a Wheatstone bridge, where the two tensile gauges on the top have equal resistance to each other, and the two compressive gauges on the bottom have equal resistance to each other.
Downward Force F = 25,000 newtons
Length L = 0.125 meters
Location of strain gauges from wall, x in = 0.100 meters
Width of beam b = .035 meters
Height of beam h = .009 meters
Modulus of Elasticity E = 200 Gigapascals
What is the normal strain in the beam εy?
