Question $5$ : $(15$ Points$)$

Plates A and B are pin connected at G$.$ Plate A weighs $4\mathrm{.}8$ kN and plate B weighs $2\mathrm{.}4$ kN $.$

a$-$ Find reactions at supports $C,D$ and E $.$

b$-$ Find the contact forces between two plates at G$.$

Answers:

$C=0\mathrm{.}06i+1\mathrm{.}45jkN$

$D=25\mathrm{.}8jkN$

$E=9\mathrm{.}94$ikN

$G=9\mathrm{.}94i+0\mathrm{.}95jkNon$ plate $B$

$G=-9\mathrm{.}94i-0\mathrm{.}95jkNon$ plate $A$
