Torsion of a thin-walled tube is considered the best method of creating a pure shear stress state in a material. Describe some of the practical problems that may arise in the torsion test of a laminated composite tube.

Using the homogeneous beam theory, develop equations for flexural strength and modulus calculations from the load–deflection diagram in a four-point static flexure test.
