WebELE Proving Rings are available in the range of 450 lbf (2 kN) to 11,200 lbf. (50 kN). Both analog and digital models are available. The repeatability of all models of Proving Ring is within 0.2% of the indicated load and the accuracy is +/- 1% of the indicated load over the upper 80% of the working range at the calibration loads. WebShear Stress = (Proving ring reading x Proving ring constant)/Acorr ii. Horizontal displacement = Horizontal dial gauge reading x Least count of horizontal dial gauge iii. Vertical displacement = Vertical dial gauge reading x Least count of vertical dial gauge 4. Shear stress at failure needs to be calculated for all three tests performed at ...

Your graph should start at the origin of the two axes. If you have zero load, you have zero deflection of the proving ring. Add load in consistent increments. For example, if you expect a total load of "X" then do increments of 0.1X. This should give you a reasonable plot of load vs. deflection of the proving ring. WebOne such proving ring is used to calibrate the concrete beam breaker. 7.1.2 In normal use, read a maximum deflection from the dial gauge during a test. This dial reading is then … how many games do baseball play
