    Failure Load Calculations

    Hi Everyone, I am trying to validate the design by verifying that the design will withstand the applied load. Just want to know what will be right to use interms of figuring out failure load. Yield stress or tensile stress? The ultimate yield only gives you the Force where it starts to deform...

    Horizontal "X" direction and Vertical "Z" direction movement

    Hi All, I have a very weird shaped static part at the moment which I am going to try to make one part to move in two axis "X" and "Z". Basically lets just say my design is an L shaped one. I am thinking of either making one of them move in two directions while the other stays the same. Can...

    Symmetrical Note on the drawing

    In our manufacturing drawings we usually have the practice of putting centre line symbol on the view and leaving a note on the drawing saying the part is symmetrical about the vertical centre line or horizontal centre line or both. Sometimes we also say that the part is symmetrical about...

    Materials Touch Temperature

    Good morning everyone, I was researching on some materials that can be easily touched at 400deg C. Presently I have some aluminium jigs that go through the oven for 4 minutes but due to the very obvious reason of high thermal mass of aluminium they are too hot to be touched by bare hands of our...
