Ever feel like your brain is one stress cycle away from total collapse? 😩 Meet the Mohr’s Circle of System Stability – the engineering diagram that just became the most relatable merch of 2026.
Instead of material failure, we’re talking human failure:
τ_max = Burnout Limit
Flow State in the sweet spot
σ₁ = Yield Threshold (that point where you’re about to snap)
Δσ = Flow Capacity
If you’re an engineer, developer, designer, or just someone who lives in the gray zone between “I’m fine” and “I’m one meeting away from disappearing into the woods,” this design is for you.
Available on tees, hoodies, crewnecks, mugs, totes, notebooks… even bucket hats (because protecting your head from system overload is important).
