    and question 14, a, ii two lifting cabels, one on each side, are required to lift a 400kg door. the steel lifting cabels are each 5m long and each has a cross sectional area of 27mm^2. the modulas of elasticity of the steel in the cabels is 230GPa. calculate the extension of each cable. *i got...

    Kaos 1, im getting the same answer but i dont get, in your working out u had 37 squared, whats with that. this is wat i did. e= LF EA e= 10,000 x 1100 (210*10^9 x 37) e= 1.415*10^-6mm = 0.0014m I just dont get that bit when u all of a sudden had 37 mm to the power of 2

    Foi?

    Ok i have heard so much about this freedom of Information application and we can get our raw marks from it. But i dont get how to actually send one in and what do you write in it. i looked at the Board of studies website and their information on the FOI is just talking shit. i just dont get it...

    Q: Compare and contrast how thrust is produced in the Turbojet and Turboprop engine Turbojet : a series of fans act like a compressor drawing the air in. the air is then compressed and thus it heats up, it is then mixed with fuel n then ignited. this air then expands rapidly. this expanding...

    its kinda hard to see. total height of the bridge is 3 m n tha distance from Rb to the end of the bridge is 14m then using that get the angle under the bridge. using alternative angles you get tha angle at the tip of the truss. then using sum of a triange = 180 then you find the angle tha you...

    Im using methods of joints in this. using the reaction Rb n finding the angle at which the structure is at. then just simple trig 2 find the hypotenuses, member AB. I think another Question will help us Describe the process and the advantages of powder forming?

    now that i do try 2 work it out insted of jut using thaa other guys answers. i did get Rb=130kn now im getting my force in member AB = 132.90 Kn Is tha right tho?

    Umm using your reactions at Rb 90 kn i got force in member AB = 92kn Arman is that the right answer? im not 2 confident with it tho

    General Thoughts: Physics

    i figured that it was a projectile and used that (delta y= u t + 0.5 a t^2) for the electron and i ended up getting time being rediculas long. i got like 3*10^6. n i was just like WTF. then i tried 2 uses the time dilation formula. im pretty sure i fuked tha up. lol. loved the astro section...

    did anyone think that the rubber band question had like nothing 2 do with physics. It wasn't 2 hard but i just think it was part of our syllabus I do engineering studies and these sort of question come up in our engineering exams.
