The T bracket BCE is supported by a pin at $C$ and attached to a deformable rod at $B.$ The external forces $P1=66kN$ and

$P2=86kN$ are applied at $D$ and $E,$ respectively. Rod $AB$ has a circular cross$-$section with diameter $d_{AB}=49mm,$ length

$a=289mm$ and orientation $=19$ as illustrated below.

Consider the following dimensions: $b=276mm,c=195mm,d=205mm$ and $e=262\mathrm{.}9mm.$

Python input:

$a=289$

$b=276$

$c=195$

$d=205$

e $=262\mathrm{.}9$

P$1=66$

P$2=86$

theta $=19$

dab$=49$

Determine the magnitude of the internal normal force in rodAB.

$F_{AB}=$

kN
