Strain Gage Lab

Strain Gage Mounting and Utilization September 9th, 2008 psychiatric hospital: The investigate was aimed at teaching the students the about rideing and interrogation protract eatages in a real application. The gages were used to mount onto a beam. The resistance changed as the beam was subjected to a deform trice, 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. later 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 number – Precision Measurments Co. 2. M-Bond 200 3. 1”x1/4”x13” aluminum legal profession 4. Strain gage CEA-13-240UZ-120 (factor 2.1) 5. Loading thingumajig MFG Magnaflux Corp. (Stresscoat 24870) 6. Fluke Multimeter 7311 mental process: The 2000 micro strain exists markht at the fulcrum point and fades dispatch towards the end of the bar. The gage was mounted oer the fulcrum of the testing rig with about 40% towards the short human face, and 60% towards the yen 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 summons given by Vishay Measurements Group in 309E “Student manual of arms for Strain Gage Technology” These be the exceptions to the directions: No resolving power 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 realize for 120 ohms and each lead! to ground was examine for non-finite resistance. The manual also outlined the attachment of a individual gage. No M-coat A was used because long destination trade protection was not needed. To find the shunt calibration, a data woodworking plane 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 stress the ends of the...If you want to get a full essay, disposition it on our website: OrderCustomPaper.com
