The App calculates the stress state in the padeye based on elastic AISC code. A scaled working page is used to analyse the stress state based on shackle position. It simultaneously calculates the stress state during simulation of the shackle position and magnitude of the force. It warns the user if the UF (Utilisation Factors) exceed unity. An intuitive UF radar is employed to plot the utilisation factor for any desired position of the shackle. Automatic simulation for ranges of shackle position, section location and angle is available to ease user in analysing the padeye. List of available shackles are presented on the data page. Initial guess of the padeye size are given at the start upon shackle capacity selection. User is able to alter the padeye size based on the requirement and material availability. The easy-to-operate drafting page is for the user to operate simple drafting tool with finger touch and drag. Report can be produced upon finishing the design (Full Version). Tracing a design drawing or a photo of actual padeye is made possible with the mobile device capability (Full Version). User can assess and review an existing design of a padeye by taking photo of the design drawing or the actual padeye (Full Version).
