Q4: Assume a 120 strain gauge is attached to the cylindrical surface of a 12 oz can
designed to hold a carbonated beverage. When the can is filled and pressurized, it
causes the walls of the can to expand, resulting in a strain of the metal can material
and, therefore, the strain gauge. If the gauge factor is 2 and the resultant strain after
the filling and pressurization process strain is 243 x 10-6
, calculate the change in
resistance of the strain gauge
