The concrete column shown originally has a relative angle of twist of 0.4 degrees when subjected to a known torsional load. After wrapping the column with a composite wrap, the new angle of twist is 0.35 degrees under the same load. Assuming the shear modulus of the composite is twice that of the concrete, find the thickness of the composite wrap. Photo by Ingolfson, public domain.
