I keep messing up the conversion of units - does anyone have a general rule I can follow? Why do we change the foot pounds to inch pounds only after the equation here while in the next post we do it before? Do we need to know about the safety factor for the test? What about other safety factors or are all steel beam calculations using 1.67 as a safety factor? Will something like this be on PDD?

First off whats the deal with telling us to use a certain formula in the question and then rearrange it in the answer? Can it still work with the original formula? Why do we convert feet to inches here before the formula while doing it after in the previous post? When I try using the original formula I get w=2000 L=(30feetx12inches)360 so 5(2000(360^4)/384E=I I =14,700 inch^3 - What am I doing wrong?

I don't understand this explanation because its very confusing to me but I guessed it right. I treated red points a and d like a free body diagram with arrows pointing towards the points as compression and arrows pointing away from the points as tension. Beam ac is going to be in tension while beam bd will be in compression because of the load. Therefore the respective points will have arrows doing the same - is this a correct way of doing this?

Do basement walls not need to be designed to resist overturning caused by earth pressure? I don't understand their reasoning behind d being incorrect

I don't remember studying anywhere in the kaplan review that you divide anything in moments - do you?

Do we need to memorize these factors when sizing members or will they be given in a question or in a reference material in the case studies? Kaplan didn't review these very well - not like ballast at least

Would a question like this come up and would we need to know these service load factors?
