Engineers test two experimental wind turbine blade designs, Design 1 and Design 2, by applying a net torque to rotate each design from rest through a specific angular displacement. The table below summarizes the applied net torque as a function of angular displacement \(\theta\) and the total angular displacement \(\Delta \theta_{\text{total}}\) for each test.

DesignNet Torque Function \(\tau(\theta)\)Total Angular Displacement \(\Delta \theta_{\text{total}}\)
Design 1Increases linearly from \(0\) to \(2\tau_0\)\(\Delta \theta_0\)
Design 2Constant torque equal to \(1.5\tau_0\)\(0.5\Delta \theta_0\)

Which of the following correctly compares the average net torque \(\tau_{\text{avg,2}}\) exerted on Design 2 and the net work \(W_{\text{net,2}}\) done on Design 2 to the corresponding quantities for Design 1?
