Hopefully someone here knows what I'm talking about, but here it goes.
I'm doing my leaving cert applied maths paper in 2 days time, and I'm stuck on this question. I can't follow the solution available on the internet, so i need someone to go through it step by step. Its Q7 in the paper here: http://www.examinations.ie/archive/exampapers/2001/LC020ALP1EV.pdf
Basically i drew up my diagram, marked in all the correct forces, balanced them horizontally and vertically, then split the rods up, and worked out the forces on each rod seperately. (Should i have done that?).
Then i took moments on each rod, and tried solving between all my equations, but i couldn't get it to work out. The online solution is here: http://www.examinations.ie/archive/markingschemes/2001/LC020ALP1EV.pdf
Any help appreciated.
