So I have to lift the engine and transmission out of my car to replace the clutch, and instead of buying a engine lift, me and my dad want to build one into the car port.
What we want is for it to be able to support 1000lbs without failing (safety factor already included)
The carport is held up by telephone poles, and we are going to span directly over them with a block and tackle or something similar.
The only thing I don't know is the breaking point of the 4x6
The span is 10ft unsupported with 1ft supported at each end. The weight will be right at the middle of the span as well. I've looked all over for data on the breaking strength and even looked for my old beam calculations from engineering class. But I still don't because the young's modulus is seemingly impossible to find for wood and even with it my formulas will only give me deflection and I don't know how much the wood can deflect before breaking. I tried finding span tables but I can't find any for a 4x6 and don't really get how to read them.
So does anyone have experience and know this information?
