Strain Gage Lab

Strain Gage Mounting and Utilization September 9th, 2008 asylum: The investigate was aimed at teaching the students the about heightening and examination protract stakes in a real application. The gages were used to mount onto a beam. The resistance changed as the beam was subjected to a turn split second, stretchability the beam face and gage. A digital readout of the gage was displayed and out loud students to measure the strain in the beam. subsequently the gage was steadfastly adhered to the beam, a 2000 micro strain moment was applied. The read-out showed the strain to be 1966 micro strain. Instrumentation: 1. Strain exponent – Precision Measurments Co. 2. M-Bond 200 3. 1”x1/4”x13” aluminum obviate 4. Strain gage CEA-13-240UZ-120 (factor 2.1) 5. Loading thingumajig MFG Magnaflux Corp. (Stresscoat 24870) 6. Fluke Multimeter 7311 subroutine: The 2000 micro strain exists ensnareht at the fulcrum poin t and fades moody towards the end of the bar. The gage was mounted oer the fulcrum of the testing rig with about 40% towards the short side, and 60% towards the large side of the beam. The solder and wires were left facing the doer at the long end of the beam.

Mounting of the gage attend a mathematical operation given by Vishay Measurements Group in 309E “Student manual for Strain Gage Technology” These be the exceptions to the directions: No issue was used for pre-abrasion, or catalyst for the adhesive. To silicon chip the circuit, a ohm meter was hooked up across the two leads to kibos h for 120 ohms and each lead to ground was ! examine for absolute resistance. The manual also outlined the attachment of a wiz gage. No M-coat A was used because long destination testimonial was not needed. To find the shunt calibration, a data shred was referenced in class received as a handout. For a 2.1 gage factor, a shunt of 1904 essential be used. Results: 2000 micro strain are applied at a single point on the fulcrum and less as you rile the ends of the...If you want to get a full essay, disposition it on our website: OrderCustomPaper.com
