Looking for someone with advanced FEA skills to create a model of a simple impact socket wrench having specific material and dimensions properties (supplied), and then simulate an air impact wrench loading on this socket for the purpose of optimizing the mass of the socket for a specific target load. Modeling the load of an impact wrench is not simple and built in features in AutoCAD are not what we want. This is not the same as a static load, hence the need for someone with the advanced knowledge to model this correctly and simulate needed conditions. Details of hammer mass inside the impact wrench are different for every brand and model, so will need to be approximated. We can supply ballpark figures of rotational load and spikes of impact typical to an average model. Resistance to spinning is based on thread friction between bolt and nut and given CoF with no lubricant. Here we can assume full tightness and allow no rotation, however some torque will still be absorbed or transferr...

This projects entails the design of a evaporation and condensation system where heat is transferred between the evaporation and condensation components. The evaporation component is essentially an insulated tank with a hot fluid that water flows into through copper pipes, absorbing heat from the fluid and evaporating the condensation component is essentially a condenser that condenses steam at 100 degrees to water at 100 degrees. These components are parts of a larger system that's being worked on, its quite a challenging project, the heat taken away from the condenser needs to be transferred back to the fluid in the tank. timeline for the project is 4 weeks, essentially all thats being done is calculations and manufacture specifications.
