## momr1958 Group Title I need help with this problem. Table L (feet) 0.5, 1.0, 1.5 T (seconds) 0.78, 1.11, 1.36 T=2 pie L/G squared Solve the formula for G. Not sure how to do this can someone help me please. 2 years ago 2 years ago

yes |dw:1322993285116:dw|

2. wasiqss Group Title

now gm can b easily made subject

3. wasiqss Group Title

sorry g**

4. momr1958 Group Title

no it is not t2 it is T=2*pie L/G squared my computer does not have the squared sign on it.

5. amistre64 Group Title

notationwise x squared is x^2

6. momr1958 Group Title

then i am saying it wrong it is the square root of L/G

7. wasiqss Group Title

i know the formula so thats y my answer is correct|dw:1322993751354:dw|

8. amistre64 Group Title

sqrt(L/G) is good :) $T=2pi\sqrt{\frac{L}{G}}$

9. amistre64 Group Title

to under the sqrt part; we have to square; they undo each other

10. momr1958 Group Title

Yes that is the way my problem is written can you help me solve for G using the table I put in on my first post.

11. amistre64 Group Title

using the table? prolly. It might mean that you want the primary root.

12. amistre64 Group Title

$T=2pi\sqrt{\frac{L}{G}}$ $\left(T=2pi\sqrt{\frac{L}{G}}\right)^2$ $T^2=4pi^2\frac{L}{G}$ $GT^2=4pi^2L$ $G=\frac{4pi^2L}{T^2}$ $G=\left(\frac{2pi}{T}\right)^2L$ gotta see if that matches up

13. amistre64 Group Title

or rather, use the values of T and L to find values for G

14. wasiqss Group Title

i did it hours b4 amistre

15. amistre64 Group Title

good, then you can tell me if im on the right track :)

16. momr1958 Group Title

All I want is to solve for G using L(ft) 0.5, 1.0, and 1.5 and T(sec) 0.78, 1.11, and 1.36 can this be done and give me a step by step on how to do it.

17. amistre64 Group Title

It can be done. and I just posted the steps for it.

18. momr1958 Group Title

But you are not sure if you are on the right track. If you are then thank you and I will see if it works out. If not on the right track then I will check some where else for the help. Sorry not trying to be rude but this is not easy for me to understand.

19. amistre64 Group Title

momr, if you have confusion with the steps, I can try to explain them. im pretty confident that I have done it correctly

20. momr1958 Group Title

Thank you I will work it out with your steps replacing the numbers for the letters. Thank you again for being patient with me.

21. amistre64 Group Title

good luck with it :) and dont feel uncomfortable in posting any question you may have.
