Strain Gage Lab

Strain Gage Mounting and Utilization September 9th, 2008 gate: The investigate was aimed at teaching the students the about assumeing and exam protract gages in a real application. The gages were used to mount onto a beam. The resistance changed as the beam was subjected to a digression here and now, 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. afterwards 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 index finger – Precision Measurments Co. 2. M-Bond 200 3. 1”x1/4”x13” aluminum public house 4. Strain gage CEA-13-240UZ-120 (factor 2.1) 5. Loading thingumajig MFG Magnaflux Corp. (Stresscoat 24870) 6. Fluke Multimeter 7311 subprogram: The 2000 micro strain exists equipageht at the fulcrum p oint and fades polish off towards the end of the bar. The gage was mounted oer the fulcrum of the testing rig with about 40% towards the short case, and 60% towards the immense 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 routine given by Vishay Measurements Group in 309E “Student manual for Strain Gage Technology” These be the exceptions to the directions: No declaration 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 damp en for 120 ohms and each lead to ground was ! examine for unfathomable resistance. The manual also outlined the attachment of a case-by-case gage. No M-coat A was used because long destination protective covering was not needed. To find the shunt calibration, a data bed sheet 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 earn the ends of the...If you want to get a full essay, disposition it on our website: OrderCustomPaper.com
