4) A truss is a structural type characterized by:a) beams connected with hinges;b) beams rigidly connected to each other;c) beams connected anyhow, not loaded transversally to their axis.5) With the Jourawski law the shearing stress components due to shear in a section:a) are constant along the direction orthogonal to the thickness of the cross section;b) vary linearly along the thickness of the cross section;c) are constant along the thickness of the cross section.6) If the shear force is not applied on the centre of shear of the cross section then:a) the section is subject to bending moment in addition;b) the section is subject to torque in addition;c) the section is subject to pure shear.

Botween each pair of vertebrae in the spinal column is a cylindrical disc of cartilage. Typically, this dioc has a radius of about 2.67 om and a thickness of about 1.71 mm. The shear modulus of cartilage is 1.2x10' N/m. Suppose a shearing force of magnitude 10 N is applied parallel to the top surface of the disc while the bottom surface remains fixed in place. How far does the top surface move relative to the bottom surface? Units: mm Number:
