The modulus of elasticity is calculated by dividing the stress by the strain, where. such as Alcoa SAG-10TM software. It is also assumed the conductor length does not change with changes in temperature or stress. It can therefore be seen as reducing the sag effect due to the increased average dynamic tension in the cable as it oscillates. Cable’s Sag & Tension Calculation. SAG10 is a sag-tension calculation software. time curve, core temperature with current, with emissivity, absorptivity, thermal conductivity etc in accordance with IEEE Std 738[5]. PGSuper can now model complex roadway alignments including multiple horizontal curves, with or without entry and exit spirals, multiple non-symmetric vertical curves, and super. Albizu 1 , A. SpanMaster software takes the user through a logical step-by-step process of information entry and produces sag and tension results for any cable span. Catenary calculations and sag-tension analysis tools enable users to design, edit and optimize transmission lines accordingly. This tool is not a substitute for the opinion of a qualified engineer and must be used with caution. pdf), Text File (. b- PLS Pole - Tubular System's Structural design and Analysis program for Steel Masts. Calculation methods conveyor belts. Finley Engineering Company, Inc. A picture of a horizontally curve conveyor is shown below - note the idlers are tilted up on the inside of the curve in order to prevent the belt from straightening and falling off the conveyor. CommScope's SpanMaster software is a tool designed for use in the calculation of sag and tension of single or multiple cable combinations under various environmental loading conditions. Calculation methods – conveyor belts Siegling – total belting solutions conveyor and processing belts This brochure contains advanced equa-tions, figures and recommendations, based on our longstanding experience. 5 shows the tension versus slack curves intersecting at a tensionof 3700 lb, which agrees with the preceding calculations.
