Hello, and sorry for my English, as I am Norwegian. I have a statics problem which I can not understand. I've taken a pic from my book: The problem asks me to find the largest bending stress, σb, in the incisions 1 and 2. I have the solution in front of me, I just don't understand what they have done with the evenly distributed force (q). Especially in incision 2, when they find Mb, they have used: Mb = FA*aA-q*2.5m*1.25. The q*2.5m I can understand, but where does the 1.25 come from? I thought it should be divided by 2? Can someone explain how this works for me?
