i know that

**=VQ/(Ib)**

*τ*now im looking for the maximum stress so i will find that at the point at the centre of the rectangle

Q=A*[tex]\bar{y}[/tex]

A=0.5*d*b

[tex]\bar{y}[/tex]=0.25*d

===> Q=0.125d

^{2}b

I=(b*d

^{3})/12

**=VQ/(Ib)**

*τ***=V*0.125d**

*τ*^{2}b*12/((b

^{2}*d

^{3})

**=1.5V/(bd)**

*τ*now d changes as a function of X

i know that

**is constant from x=0 to x=L**

*τ*but V is constant throughout and so is b, so how can this be?

i tried making a differential equation where i know d(0)=do and d(L)=0 using d

**/dx=0 but really didnt manage**

*τ*
