How to answer 2?

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. Problem 2. A chord, with its supports at A and B, bears a load of 10 kN and a load of W. What should be the value of W so that CD remain horizontal? 60° 30° w Problem 3. Reduce the system of forces in the belts shown to a single force at O and a couple. Forces are either vertical or horizontal. Inner radius = 1 foot, radius of bigger pulley from O = 2 ft. 20 Ib 40 Ib 30 1b 15 Ib
