  • Build Stronger, Sag-Proof Shelves | Popular Woodworking ...

    Designing sag-proof shelves. A shelf sags in two stages. There''s a small sag when you first put weight on the shelf. This sag, or deflection, increases as more stuff is loaded on the shelf over the years. The shelf keeps on sagging, a little more each year, because wood slowly but surely changes shape under a load.

  • Calculating Sail Power | Boat Design Net

    Jan 25, 2006· Power boats have a fixed amount of power available, so you get the performance from the point where power required = power available. With a sailboat, it''s only after you already know the performance that you can go back and figure out what the power is. Instead, it''s much more straightforward to look at the balance of forces and moments.
