We report the separate response of the critical temperature of the nematicphase transition $T_{\rm S}$ to symmetric and antisymmetric strains for theprototypical underdoped iron pnictide Ba(Fe$_{0.975}$Co$_{0.025}$)$_2$As$_2$.This decomposition is achieved by comparing the response of $T_{\rm S}$ touniaxial stress and hydrostatic pressure. In addition to quantifying the twodistinct linear responses to symmetric strains, we find a quadratic variationof $T_{\rm S}$ as a response to antisymmetric strains $\epsilon_{\rmB_{1g}}$=$\frac{1}{2}$($\epsilon_{\rm xx}$-$\epsilon_{\rm yy}$), exceeding thenon linear response to symmetric strains by at least two orders of magnitude.These observations establish orthogonal antisymmetric strain as a powerfultuning parameter for nematic order.
