    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 cant figure that one.

    i want to get the T.
    please help me.

    I don't know what this about, but it seems simpel algebra: All terms are divisible
    by L so you can factor it out, ant then you add the last two terms.

    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.
