Unformatted text preview: Lecture 13, Chapter 5.55.7 Instructor: A Rezaei Today’s Objective: Students will be able to: Students will be able to: a) Identify support reactions in 3D and draw a free body diagram, and, b) apply the equations of equilibrium. SUPPORT REACTIONS IN 3D EXAMPLE 1 Given: The cable of the tower crane is subjected to 840 N force. A fixed base at A supports the crane. Find: Reactions at the fixed base A. Problem 1 Draw the FBD for each pipe separately and each one alone. Problem 2 Draw the FBD for each object. Problem 3 Determine the vertical and horizontal reactions for the beam loaded as shown. Problem 4 Determine the tension in the cord and the reactions at A. Problem 5 The link shown in the figure is pinconnected and rests against a smooth support. Compute the horizontal and vertical reactions at A. Problem 6 Determine the tensions in cables BC and BD and the reactions at the balland –socket joint at...
