Strain Gage Lab

Strain Gage Mounting and Utilization September 9th, 2008 portal: The investigate was aimed at teaching the students the about raiseing and interrogatory protract thrones in a real application. The gages were used to mount onto a beam. The resistance changed as the beam was subjected to a crimp s, 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 immobilise 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 bearinght at the fulcrum poin t and fades finish off towards the end of the bar. The gage was mounted oer the fulcrum of the testing rig with about 40% towards the short facial expression, and 60% towards the yearn 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 mapping given by Vishay Measurements Group in 309E “Student manual for Strain Gage Technology” These be the exceptions to the directions: No consequence 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 visualize for 120 ohms and each lead to ground was examine for sempiternal resistance. The manual also outlined the attachment of a virtuoso gage. No M-coat A was used because long destination apology was not needed. To find the shunt calibration, a data airplane was referenced in class received as a handout. For a 2.1 gage factor, a shunt of 1904 essen tial be used. Results: 2000 micro strain ! are applied at a single point on the fulcrum and less as you construct the ends of the...If you want to get a full essay, disposition it on our website: OrderCustomPaper.com
