Question

Given that for a channel section, the width of flange = b, the depth of the web between centres of flanges = h, the thickness of flange = t, the moment of intertia of the channel about the axis of bending = I, the distance of the shear centre outside the channel section from the mid- thickness of the web is

• A. $\frac{t{h}^2{b}^2}{I}$
• B. $\frac{t^2{h}^{2}b}{4I}$
• C. $\frac{t{h}^2{b}^2}{4I}$
• D. $\frac{t^{2}h{b}^2}{4I}$

Answer 1

The correct option is C $\frac{t{h}^2{b}^2}{4I}$

$e=\frac{b^2{h}^{2}t}{4I}$
