(6) There are many kinds of polyethylene foam, each with different properties. The low density polyethylene foams (as seen in this video) are very flexible. Remember: in solid mechanics, "flexible" just means that in comparison to other materials, the material deforms quite a bit, relative to the stress. For torsion, the material property that relates to stiffness is the shear modulus (or modulus of rigidity), G. We'll say that G = 6 MPa. a) Complete the FBD. b) Compute the shear stress at Point B. c) Illustrate it on a stress element. d) Report the shear strain at B (in radians). e) Compute the rotation of the top plane. f) Compute arc length s.
