a component parallel to a and a component orthogonal to a: c = aλ+ ˆc, with aT ˆc= 0. • If λ > 0, the problem is unbounded below. Choose x = −ta, and let t go to infinity: cTx = −tcTa = −tλaTa → −∞ and aTx−b = −taTa−b ≤ 0 for large t, so x is feasible for large t. …

If the seals are perpendicular to the entries or if there are stoppings in the cross-cuts, then there would be significant debris in the cross-cuts.

ocw.mit.eduBut why exactly perpendicular? Work done on an object changes its potential, so it can take no work to move along an equipotential line. Work is given by the dot product of force and displacement. For this to be zero, the force must be perpendicular to the displacement, that is, force (and hence fields) must be perpendicular to equipotentials.
