willem2 thanks for your response. that is one of the example in my book. can you please explain it a little bit more. maybe a step by step? please. how come that all the L are gone and the W are only 2 then it becomes 3. i will appreciate it very much.

can you please explain why this (TLsin30.0° − w((L/ 2)cos30.0°) − w(Lcos30.0°) = 0) becomes this T sin30.0° − (3w/ 2)cos30.0° = 0 i though i can do all the transpose and other stuff. but i can't figure that one. i want to get the T. please help me.

how sad.. :( no ones helping me..

i try to solve question number2 and my answer is. -T1 = 75 T2=60 is it correct?

Homework Statement Please help me to draw free body diagrams of the following. 1.Find the tension T in each cable and the magnitude and direction of the force exerted on the strut by the pivot in each of the arrangements in fig. 11.23 in each case let w be the weight of the suspended crate...

Homework Statement an antelope moving with constant acceleration covers the distance between two points 70.0 m apart in 7.0 s. Its speed as it passes the second point in 15.0 m/s . a) what is its speed at the first point? b)what is the acceleration? Homework Equations what do you...

ok! now i know.. and now i understand those basic parts. thanks! im waiting for more than hours.. haha! thank you very much.

you mean like this? the truth is i only know how to get the other angles but i don't know where toplace them. thanks for the information now i know where to place them. is this correct? http://img341.imageshack.us/img341/1923/41728774.png http://g.imageshack.us/img341/41728774.png/1/...

ow I am sorry.haha! i forgot to tan-1 it.. the answer = 56.31 deg. :) for this question c(->) = 125m/s 75deg north of east e(->) = 500 kg m/s (hey, what should i do in that kilogram meter/second? thatas what makes me confuse) 18 deg south of east. s(->) = 707m 26 deg west of...

for letter a. i just subtract the 800N. with 600N. so i the answer will be 200N south. :) thanks for clarifying my answer. the theta for letter b. will be 0.03 right? 450/300 = 1.5 tan(1.5) = 0.03.. im pretty sure that I am correct.

thanks now i know.. heres the question: thanks modulus, thanks tiny-tim. I am more sure of my answer by now. for a) 800N. due south and 600N. due north. i think i don't need to find the theta. because it will be like these. ...800N due South. ..^...l ..l...l ..l...l ..l...l...

is this correct? 0.03?? in the example of my teacher. she use tan-(opposite/adjacent)

so it mean that iam correct? o:) by the way.. what is the easiest clue for me to know what is the adjacent and opposite. its easy to know the hypotenuse but i don't have any clue on how to know the adjacent and opposite.

thanks modulus, thanks tiny-tim. I am more sure of my answer by now. for a) 800N. due south and 600N. due north. i think i don't need to find the theta. because it will be like these. ...800N due South. ..^...l ..l...l ..l...l ..l...l ..l...V 600N due North the answer will be 200N...

ow. sorry for that. after researching on how to get angle for right triangle i m pretty sure this is correct. C= 125 m/s 75 deg North of East http://img228.imageshack.us/img228/8565/69844695.th.png is this correct? am i wrong in my answer 111.80? i though that i will need to...
