3....MPa use this equation (sigma)max=(sigma)avg+R

I am having problems with the first part. Because I found the deflection as: delta=((P*(l_AB)^2)*((3*(l))-l_AB))/(6*E*I) But l is not permitted, so I replaced l=0.95[m]. but I obtained a wrong answer. My deduction is correct? What is my error? Please, som...

I worked with this equation: sigma=C_2*E_s*0.1^2 = 750000[Pa] Then for the energy: U=sigma*s_densification= 750000*0.8=600000[J/m^3] But the answer is incorrect. Also, I know that E=C_1*E_s*0.1^2 =15[MPa] But I don't know how can I use it. Some help pleas...

Some help please. I really don't know what is my error
