Question 1 A short post AB has a commercially manufactured eyebolt screwed into its end. Three cables attached to the eyebolt apply the forces shown.
a) Determine the resultant force applied to the eyebolt by the three cables, using a Cartesian vector representation.
Question 2
Forces F→, P→ and Q→ are given using a variety of different forms of orientation information that are commonly encountered.
(a) Write a vector expression for each force.
(b) Determine the resultant of the three forces.
(c) determine the direction angles for the resultant.
