Screw vs DC Power Cable Size Calc

The most easiest mobile calculation of tightening and loading of screw joints for reliable engineering of screw joints. The App is based on worldwide approach of guideline VDI 2230. Just select minimum of parameters and see the resulting tightening diagram as well as the force elongation diagram. As a small version of the huge software package Screw-Designer it follows the same input strategy: starting with default values and refining to the own application. An elastic tightening specification is provided for your screw selection which san be modified. Corresponding safety-factors are provided for tightening and operating state. With this convenient tool it is possible to make a fast pre-design of your fastening systems. For limitations see help section of Screw-Designer Basic. If you have to engineer a fastening system in detail, use Screw-Designer full version or contact us, because optimized fastening systems are getting more and more important and can save a lot of money. New: Factor-approach to preload relaxation. It extents the traditional preload loss by seating. Resulting from this much more reliability is achieved, especially when using light materials and/or high preload level. Units can be changed between metric and imperial, so a comparison of thread systems is easy. Following thread profiles are covered: M3 - M64 (coarse and fine), MJ, UNC, UNF, UNJF Following materials for the screw can be selected: Steel 4.8 - 16.8, Aluminum Following materials for clamped part can be selected: Steel, Aluminum, Cast Iron, Magnesium, Plastics The start page provides alternating important tips for engineering design of screws.

DC Power Cable Size Calculator are electrical calculator to find approximate wire gauge/size based on the length of the wire, the voltage and the current (in amps). Features: - Instant calculation - Result are copy able to other app - Formula are include as reference - Support various unit for each input Cable sizes are important for low voltage battery cables, wind turbines, solar panels and load cables. Common reasons for low voltage (12v, 24v or 48v) system faults are voltage drops through incorrectly sized cables. It can be very dangerous If the cable is too small, as the cable will heat up and potentially cause a fire. On contrast an oversized cables might cause energy or money waste. Formula: VDI = (Amps x Distance)/(%Volt Drop x Voltage) VDI - Voltage Drop Index (a reference number based on resistance of wire) Distance - One way wiring distance in feet %Volt Drop = acceptable voltage drop Cable Size by cross-sectional area [Cooper] mm² = VDI x 1.1 The voltage drop value will vary depending on your application. The standard 2% are use to ensure delivering full potential to any needed electrical source. And 5% or more voltage drop is more common in automotive applications. Safety Guide: - Cable sizes should only be used as a guideline and all figures should be checked against the manufacturers data sheet. - Cables should be fused / current protected to their max rating or less.
