1. ### Wind Turbine Project

Good day! I was thinking of building a horizontal-axis wind turbine and testing various blade designs but i can't afford a generator to test the power output of each variation. Is it sensible/possible to get the output without a generator? Can equations in finding torque be used? Thank...
2. ### Converting Piecewise function to Heaviside equation

Thank you so much for the response good sirs :smile: Sorry for that sir Bruce. I missed to proofread that part..that's suppose to be H(t) = t2 - u2(t) Sorry for that notation sir Simon. i was just following the notation uc(t) in preparation for an inverse Laplace transform: L(uc(t)) =...
3. ### Converting Piecewise function to Heaviside equation

Good day! I would just like to ask on how to convert a particular piece wise function to a heaviside equation. For a function, f(t) = t2 if t < 2 t - 1 if t >= 2 the heaviside equation would be, H(t) = t + (t-1 -t)u2(t) or H(t) = t - u2(t) but i can't comprehend on...
