Consider a symmetric laminated beam with three laminae of equal thickness. The top and bottom laminae are made out of steel. The center one of aluminum.

1. Make a sketch (not to scale) of the deformed shape of a beam subject to a positive bending moment Mx. Make sure your drawing shows the thickness of the beam; i.e., do not idealize the beam by a line.

2. On the same drawing, sketch the distribution of strain (not to scale).

3. On a similar drawing, sketch the distribution of stress (not to scale).
