MAE 3113 MEASUREMENTS AND INSTRUMENTATIONS FALL 2006 Lab 7 (Two-week Lab) STRAIN GAGE Static and Dynamic Introduction: The measurement of strain both static and dynamic plays an important role in the design and safety of most all objects. If the safety of an object is in question then there may be a need to perform both static and or dynamic load conditions. For example; an aircraft fuselage must be able to withstand the large number of cycles of undergoing pressurization. A building must be able to withstand by the static loads of its own weight as well as that which is induced by the wind. Objective: As a group, you will learn how strain gages are installed, how they are connected to a bridge- amplifier unit, and how they can be used to make useful measurements of different strain or deflections. 1. Build a Wheatstone bridge by connecting four identical resistors (range 200-1000 Ω ). a. Measure the resistance of each resistor and record the value to 4 decimal points. b. Arrange the resistors to create a Wheatstone bridge. The resistors should be arranged such that the ratio of each pair of resistances is close to the other. For example, if the four values are 120.1, 119.8, 120.2, and 119.9, make sure that you connect the two lower values together and then connect the higher values together. This should produce the lowest voltage across the bridge.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
