Circ shear by the offset method I am interested in an equation that will give me the offset needed for a circumferential shear wave inspection on a cone. I have come up with one but I am not sure if it is right. Offset=radius*sin(incidence angle)/cos(cone angle from verticle) I have also come up with equations for triple indexing up the cone to maintain the proper offset. Y=Index*Sin(incidence angle)*cot(cone angle from horizontal) X=Index*cos(cone angle from the horizontal) Z=Index*sin(cone angle from the horizontal) Can anyone verify these equations.
