Hankinsons formula
WebHankinson's equation (also called Hankinson's formula or Hankinson's criterion) [1] is a mathematical relationship for predicting the off-axis uniaxial compressive strength of wood. The formula can also be used to compute the fiber stress or the stress wave velocity at … WebHankinson's Formula Situation The truss shown in is made from timber Guijo 100 mm × 150 mm. The load on the truss is 20 kN. Neglect friction. Allowable stresses for Guijo: Compression parallel to grain = 11 MPa Compression perpendicular to grain = 5 MPa Shear parallel to grain = 1 MPa 1. Determine the minimum value of x in mm. 2.
