what was the original problem and the given?
Hi there you guys can see the problem here
PicPaste - 20140824_105133-N1SKFQCV.jpg
Actually when I solve it i get something else
16MC/1.5 + 15360 / 4*1.5 + 2MC*4 + (3*60*4^2) / 6
I later get
10,66 MC + 2560 + 8MC + 480
which gives me
MC =-162
what have I done wrong if so,could someone show me how to solve it properly? Thank you
The information you have given is insufficient to solve anything. For example, sometimes it appears that L = 8, but sometimes it appears that L = 4. If some of the variables in the first line are assigned values, what are those assigned values?
Moreover, the transition from the first line to the second line is very odd. For example, how does
$L = 8 \implies \dfrac{2M_cL}{6EI} = \dfrac{2M_c * 8}{6EI * 1.5}?$
Of course, maybe L = 4. How does $L = 4 \implies \dfrac{2M_cL}{6EI} = \dfrac{2M_c * 8}{6EI * 1.5}?$
The third line is not even an equation. But it seems to imply that EI = 1. Is that correct?
The fourth line introduces some undefined variables that have not been seen before.
How are you using periods and commas? It appears that you are using the European convention sometimes and the American convention sometimes. We can probably cope with either convention, but not a mixture.
