Question 1 – Coplanar or 2-dimensional force vector resultants<\/h1>\n

(Note – Labelled Problem 2-8) Find the angle \u03b8\u00a0 for connecting member A to the plate so that the resultant force of FA and FB is directed horizontally to the right.<\/p>\n

Hint:\u00a0 Resolve FA and FB into Cartesian or i j k vectors.<\/p>\n

What is the magnitude of the resultant force?<\/p>\n

 <\/p>\n

FA = 8 kN<\/p>\n

FB = 6 kN<\/p>\n
