omg i got it... the 54 blah blah blah Newtons is too much for the wire AC to handle as in it produced a pressure over 150 X 10^6 N/m^2... i did it on my calc and am too tired to do it again and post the answer. thanks guys... you're the best (Y) extra kudos to stewartcs

Homework Statement The figure below shows a weight, W, supported by two wires, the stresses n the wires AB and AC are not to exceed 100M N/m^2 and 150 N/m^2 resp. The X-sectional Area of AB is 400 mm^2 and AC is 200 mm^2. you are required to calculate the largest load which can be supposted...

the lecturer showed us a pretty neat way to handle these units... Nsm/Kg -> since N= Kg/m^2 then units = m^2/ S very late don't have time to rbeak down

hey guys I am new to the forum... i am a first year civil engineering student trying to do a second year course over this summer holiday. for fluid mechanics i was given this h/w problem. could you please tell me if I am correct and if not make explain where i went wrong and how to correct it...

many thanks.,

hey guys. I am not sure if this has to go here. but could someone explain to me what exactly is the second moment of area. i mean what exactly is it what could it help you find and stuff?

maybe jesus christ was really an ancient astronaut.

hurray for b00bies i found it. this link helped sort the voltage divider thing for me http://www.allaboutcircuits.com/vol_1/chpt_6/1.html sorry guys no offence or anything. but i haven't understood quite clearly from the way you've explained. however. ur links and stuff were good reads and...

aw man. i think that's my problem right there. i don't know about voltage divider equatiosn and stuff.

oh okay okay i udnerstand that. but i don't quite understand the actual equation e = V1R3/(R1 + R3) as in how it was derived.

how about this. instead of expanding on and on. it stops at some point. and starts to shrink. o.O would everything go backwards. would time reverse itself.

Homework Statement hey guys. I am new to the board. I've seen this problem on a website of which i'll list below. I am not sure how came up with that formula for e. http://hyperphysics.phy-astr.gsu.edu/HBASE/electric/thevenin.html -> is the link to the page. i understand the rest of...
