Now learn Live with India's best teachers. For example, if the diameter is two inches, divided by two to get a one inch radius, square it and get one inch squared, and multiple by pi to get 3.14 inches squared. Here is how the Total elongation of bar calculation can be explained with given input values -> 545.4545 = (6000000*2)/ (2*11000000). Rod elongation is a critical consideration in the design of threaded rod systems carrying uplift loads from roof to wall anchorage or shearwall overturning. When designing cable or wire rope systems, the amount of stretch that will occur when a force is applied is an important consideration. Already a Member? Stress = Force/Area // . The formula for Hooke's law specifically relates the change in extension of the spring, x , to the restoring force, F , generated in it: F = kx F = kx. In the formula as mentioned above, "E" is termed as Modulus of Elasticity. Now here the circular motion is not perfectly vertical, so we have to apply the general formula of tension for an object in a circular motion. T=(Lx) LW Elongation = yLStress= LAy(Lx)Wdx Total elongation = OL LAy(Lx)Wdx= LAyW (Lx 2x 2) 0L= 2AyWL Now, W=ALg Putting it in there: L= 2AyAL 2g= 2yL 2g Will Nondetection prevent an Alarm spell from triggering? The gauge length is the reference length used in the elongation calculations. Let weight of the rod is W. Consider a small length dx of the rod at distance x from the fixed end. Square this number and then multiply by pi. On data sheets, you find a tape's elongation at break as a percentage. The tension T in element equals the weight of rod below it. There isn't a huge variation within this class of wire rope. A = cross-sectional area of bar (in. Keep the following in mind when you do your calculations: There are two forms of stretch in cable and wire rope: Structural Stretch and Elastic Stretch. Structural Stretch in Loos & Co., Inc. products is less than 1% of the total cable length.
