anyone?

for AlNi3 i have 7.41 g/cm^3 and for AlNi, 5.955 g/cm^3 let me know how if i made a mistake or not, couldn't find anywhere to double check them with online

took me forever but DB is 103.97N and DA=DC=294.4N finally! thanks a lot, took 5 hours but i got it

im a little rusty at this but i got Db=452.4N and I am pretty sure that isn't right, can you lead me in the right direction solving for 3 variables

i thought Da and Dc were suppose to be the same so I am confused on how to move on from this stage

Tdc=CD(0.433i-0.25j+0.866k) Tdb=DB(-0.32i-0.383j+0.866k) Tda=DA(-0.32i+0383j+0.866k) so are those all correct?

so Tdc along z-axis would be DCcos30, then along y-axis, (CDsin30)(cos120), and x-axis (CDsin30)(sin60) ? Tdc=CD(0.433i-0.25j+0.866k)?

Well the 600n is simply F(DO)=600k, but I am having troubles breaking up the chords into its components and yes, we've just begun on Moments/torques as well. the reason i first assumed they were equal is due to the 100 degree spacing from the centre chord, I am just having trouble relating...

im really hoping someone can reply tonight if possible, I've been working on this but nowhere...any help?

can i do this? 600=(T1+T2+T3)cos30 and assume all the tensions are the same? then 600/3cos30=T then, T= 230.94 N? or 173.205N?

ok update, I've solved this question on my own, still having trouble with my other one though, trying special triangles https://www.physicsforums.com/showthread.php?p=1449317

well escape speed is the minimum speed to break the gravitational pull, so if you look at it like a derivative, the minima will b eequal to 0 where you get Vf is 0 i think can someone help me with my questions as well? https://www.physicsforums.com/showthread.php?t=167738 and...

is it possible that both B and C could have the same force of 500N?

i also tried splitting it into components along the x and y axes, but it didnt end up helping me get different answers for the tensions
