Consider the portal frame as shown below

The magnitude of force P that should be applied to produce the above shown final moments is _______ kN.
16.5

Open in App

Solution

The correct option is A 16.5
Applying shear equation,

$H_{A} + H_{D} = P$
$[\frac{P}{3} + (\frac{15 + 9}{3})] + [\frac{7 + 5}{4}] = P$

$8 + 3 = P - \frac{P}{3}$

$\Rightarrow \frac{2 P}{3} = 11$

$\Rightarrow P = 16.5 k N$
