Problem 1. A concurrent force system in space consists of three forces with the following descriptions: a. Force Q1, which acts through the origin and the points x=3, y=4, and z=2, has a magnitude of 110 kN b. Force Q2, acting through the origin and points x=4, y=1, and z=-2, has a magnitude of 65 kN. c. Force Q3, which acts through the origin and points x=2, y=-3, and z=3, has a magnitude of 85 kN. Determine the x-, y-, and z- components of the resultant force. Please show your FBDS and complete solution. Also show the working equations.
