13 Sections 2-1 to 2-4 Vector addition of 2 dimensional or coplanar forces.
Question 1 – Coplanar or 2-dimensional force vector resultants
(Note – Labelled Problem 2-8) Find the angle θ for connecting member A to the plate so that the resultant force of FA and FB is directed horizontally to the right.
Hint: Resolve FA and FB into Cartesian or i j k vectors.
What is the magnitude of the resultant force?
FA = 8 kN
FB = 6 kN
Question 2 – Coplanar or 2-dimensional force vector resultants
Note: Labelled as Problem 2-20
If φ= 45.0o, F1 = 5 kN and the resultant force is 6 kN directed along the positive y axis, determine the required magnitude of F2 and its direction angle θ .
Question 3 – Determine the resultant force
Determine the magnitude and direction measured counterclockwise from the positive x axis of the 3 forces. F1 = 500 N and the angle at shown is 20.0o.
