Answer:
1.933 KN-M
Explanation:
<u>Determine the largest permissible bending moment when the composite bar is bent horizontally </u>
Given data :
modulus of elasticity of steel = 200 GPa
modulus of elasticity of aluminum = 75 GPa
Allowable stress for steel = 220 MPa
Allowable stress for Aluminum = 100 MPa
a = 10 mm
<em>First step </em>
determine moment of resistance when steel reaches its max permissible stress
<em>next </em>: determine moment of resistance when Aluminum reaches its max permissible stress
Finally Largest permissible bending moment of the composite Bar = 1.933 KN-M
<em>attached below is a detailed solution </em>
