I need the answer as soon as possible
Extracted text: The cross-section of a composite beam made of aluminium and steel is shown in the figure. The moduli of elasticity are E_{a} = 75GPA and E_{s} = 200 GPa. Under the action of a bending moment about z-axis that produces a maximum stress of 50 MPa in the aluminium, what is the maximum stress o in the steel? %3D %3D Aluminium Steel: 30 mm 1- - ww 08
