In the following exercises, write the calculation of each step exactly like the those in the powerpoint. Draw the deflected shape of each step from which you calculate the values. $($The numbers should be written with four digits after the decimal point$).$ Each question has $2$ marks.

Exercise $2-$ Using the modified Newton$-$Raphson method, analyze the following structure as geometric nonlinearity. $($Using the displacement criterion, consider the accuracy criterion for convergence to be ${10}^{-3}$ in the iteration steps$).$: $$:

Exercise $3-$ Using the Newton$-$Raphson method, analyze the following structure in a geometric nonlinear way. $($Using the force criterion, consider the accuracy criterion for convergence to be ${10}^{-3}$ in the iteration steps$).$

In both exercises:

The supports are fixed and two truss members have the following specifications:

$E=200$

$A_1=2,$ cross section

$A_2=1$

$L_1=90$
