can you please help me this is a preparation for my Qual. part c is what actullay confuses me thank you in advanceThe material has a linear viscoelastic behavior with elastic and steady$-$state creep strains, similar to the model

given below.

If initially, $E1=3$GPa and ${}_1={10}^5$GPa, determine $($a$)$ the maximum stress in the beam, $($b$)$ the initial elastic

deflection when the load is applied, and $($c$)$ the deflection after one day.

Hint:

$I_z=\frac{t{h}^3}{12}$

$I_y=\frac{h{t}^3}{12}$

$M_B=\frac{PL}{4},v_B=\frac{P{L}^3}{48EI}$: A simply supported beam with L $=100$ mm $,$ t $=10$ mm$,$ h $=5$mm$,$ is loaded with a load of P $=20$ N

at the center point B$.$
