“…Only Equation (3-11a), the 6,, term, is used for the derivation of Equation (3)(4)(5)(6)(7)(8)(9)(10)(11)(12) because the relieved radial strain, 6,, , is known to be significantly greater than tangential strain, 6,. As a result, commercial strain gage rosettes are designed with radially oriented grids as shown in Figure 8.…”
