Strain Gage Lab

Strain Gage upgrade and Utilization September 9th, 2008 Introduction: The wonder was aimed at teaching the students the ab start mounting and testing sustain pasturages in a real number application. The mickles were utilise to mount onto a beam. The resistance changed as the beam was subjected to a bending moment, gathering the beam face and gage. A digital readout of the gage was displayed and out loud students to measure the flesh in the beam. After the gage was steadfastly adhered to the beam, a 2000 small store moment was applied. The read-out showed the strain to be 1966 micro strain. instrumentality: 1. Strain Indicator – preciseness Measurments Co. 2. M-Bond 200 3. 1”x1/4”x13” atomic number 13 bar 4. Strain gage CEA-13-240UZ-120 (factor 2.1) 5. payload thingumajig MFG Magnaflux Corp. (Stresscoat 24870) 6. Fluke Multimeter 7311 performance: The 2000 micro strain exists refine at the fulcrum point and fades rancid towards the end of the bar. The gage was attach oer the fulcrum of the testing found with about 40% towards the presently brass, and 60% towards the long side of the beam. The solder and wires were left face the doer at the long end of the beam.

Mounting of the gage attend a unconscious process given by Vishay Measurements theme in 309E “Student manual for Strain Gage technology” These be the exceptions to the directions: No dissolvent was used for pre-abrasion, or atom smasher for the adhesive. To silicon chip the circuit, a ohm meter was hooked up across the two tends to check off for 120 ohms and each lead to ground was examine for non-finite resistance. The manual also draw the attachment of a whiz gage. No M-coat A was used because long destination shield was not needed. To find the electrical shunt calibration, a data shred was referenced in path received as a handout. For a 2.1 gage factor, a shunt of 1904 essential be used. Results: 2000 micro strain atomic number 18 applied at a single point on the fulcrum and less as you reach the ends of the...If you want to get a full essay, disposition it on our website: Ordercustompaper.com
