Avertebra is subjected to a shearing force of 535 n. find the shear deformation, taking the vertebra to be a cylinder 3.00 cm high and 4.00 cm in diameter. the shear modulus for vertebrae is 8.00 × 1010 n/m2.

When the displacement of a mass on a spring is 12a the half of the amplitude, what fraction of the mechanical energy is kinetic energy? at what displacement, as a fraction of a, is the mechanical energy half kinetic and half potential?
