Hi, I'm mechanical engineering student, and I'm working on project and one of the questions I've got is to plan a deep drawing process of a box and basically the demand is that I have to use a formula of drawing force of a cup and develop it to suit a rectangle shape and I have zero clue how to do it hope you guys will be able to help me out. This is the formula I need to use : 𝐹𝑚𝑎𝑥 = 𝜋*𝑑𝑝*𝑇*𝜎𝑢𝑡𝑠 [( 𝑑0/𝑑𝑝 ) − 0.7] Thank you
