la (AC X W) = [(2/3) i + (2/3) j (1/3) k] ( 5400 lb ft) k = 1800 lb ft 1800 lb ft = la (AE X T) Using the commutative property for the mixed triple product: 1800 lb ft = T (la X AE) This shows that the projection of T onto the vector (la X AE) is constant, thus T will be minimized when it … ................
