I am taking this math class and we are now doing these statics problems and I have no clue what is going on, as I have never taken a physics class. I was hoping if someone could just explain on how I can put these two word problems into a equation because I have no problem with the math portion or it, I just have a hard time understanding word problems. Anyway if anyone can help me I will greatly be appreciated.

The first problem is,

A horizontal bar of negliglible weight hangs from two cables, one at each end. When a 624-N force is applied vertically downward from a point 185 cm from the left end of the bar, the right cable is seen to have a tension of 341 N. find the length of the bar.

One of the main problems is I have no clue what the N stands for or to even start, my book has one example and it is no where the same type of problem that it shows.

The second problem is,

A uniform horizontal beam is 19.80 ft long and weighs 1360 lb. It is supported at either end. A vertical load of 13,510 lb is applied to the beam 8.450 ft from the left end. Find the reaction at each end of the beam.

Again I don't what to do, I just need a explanation or if someone knows of a tutorial or sample problem to help me answer these two problems. Like I said I have no problem with the math portion it is extraction the word problem into an equation to solve the problem.

Any info will greatly be appreciated.

Thanks Chris
