Response to the following problem:
Consider a homogeneous, isotropic beam.
1. Make a sketch (not to scale) of the deformed shape of a beam subject to a positive bending moment Mx and positive axial load Nx. 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).
