Weight Between Two Pulleys: Does a Right Angle Move It?
A pulley sketch questioning the load carried by cords meeting at a right angle
A quick mechanics sketch: a long cord runs over two pulleys, labeled n and f, with equal weights (4 and r) hung at its ends and a heavier weight (8 and m) slung between them, so that the cords meeting at m appear to form a right angle. Leonardo poses the question whether the central weight 8 is moved, that is, supported or displaced, by the cord n m when that angle is right.

Does the right angle at m carry the central weight 8?
A cord over two pulleys (n and f) carries equal end weights 4 and r and a central weight 8 and m, with the converging cords at m describing what looks like a right angle. Leonardo asks whether the weight 8 is moved by cord n m when that angle is right.
