This is a practice exercise for one of my subjects. Currently I want to simulate this setting (automatic chicken feeder). My product frequently breaks at the arrow position. The material is PP (Polypropylene) plastic (the pipe part is steel). I want to simulate the broken position and the direction of improvement? Anyone who has a way to handle this can help me more (where should I put contacts...
