Hello,

Can anyone check if my answer for part (a) is correct and help me out for part (b)?

Below is the question and answers :.

Thanx you very much.. - May 18th 2009, 10:41 AMOpalg
That looks correct. You could simplify the result a bit, to write it in the form $\displaystyle y=\frac{W}{24EI}(3lx^2-2x^3-l^3)$.

For (b), the maximum deflection occurs when x=0. So just put x=0 in the answer to (a). - May 18th 2009, 08:30 PMNiCeBoY
yeah but what to do with the value of E,I and W?

where do i get them please?

oh ...

i thought we need to remove W because it is said in the question that we should neglect the weight of the beam.

so the answer for the second part is :

$\displaystyle

y=-\frac{WL^3}{24EI}

$

This is the final answer yeah?
