Problem
A rigid body experiences a torque τ(θ) such that τ(−θ)=−τ(θ) for every angular position θ. The body is rotated quasistatically from θ=−0.80rad to θ=+0.80rad. Describe whether the net work done by the torque during this motion is positive, negative, or zero, and briefly explain your reasoning.
