<strong>FE</strong> Exam <strong>Review</strong> St<strong>at</strong>ics Jan. 31, 2013 Kurtz<strong>FE</strong> Exam – St<strong>at</strong>ics <strong>Review</strong>Classific<strong>at</strong>ion of Problems Vectors Concurrent Equilibrium (Equilibrium of a Point) Moments, Resultant Forces, Equivalent Systems Rigid Body Equilibrium Trusses, Frames, Machines Internal Forces and Moments Friction Centroids and Moments of InertiaVectors1. Determine the angle between the two cords.2. Forces are transmitted by two members to pin A. If the sum of these forces is 700 lbs directed vertically, wh<strong>at</strong> are the angles and ?3. The cables <strong>at</strong>tached to the screw eye are subjected to the three forces shown. Express each force as a Cartesian vector anddetermine the magnitude and coordin<strong>at</strong>e direction angles () of the resultant force.Page 1 of 5
<strong>FE</strong> Exam <strong>Review</strong> St<strong>at</strong>ics Jan. 31, 2013 KurtzConcurrent Equilibrium (Equilibrium of a Point)4. Determine the unstretched length of the spring if the block has a mass of 5 kg and rests on a smooth plane5. Determine the force P th<strong>at</strong> must be applied to the cord in order to pull the post out of the ground if the post is removed by a 400-lbvertical force.Moments, Resultant Forces, Equivalent Systems6. Determine the moment of the force about point O.7. Replace the loading shown with an equivalent force and couple <strong>at</strong> point A.Page 2 of 5
