1: Consider the force system exerted on the box as represented in Figure P6.3.1. The force system consists of ten forces with lines of action and magnitudes as listed in Table P6.3.1. Let the dimensions of the box be 12 m, 4 m, and 3 m, as shown. a. Express the forces F₁,..., F₁ in terms of the unit vectors n₁, n₂, and n, shown in Figure P6.3.1. b. Find the resultant of the force system expressed in terms of n₂, n₂, and n. c. Find the moment of the force system about O (expressed in terms of n₁, №₂, and n₂).
