Enrol to our Review Center: https://www.facebook.com/share/1AC24W... SITUATION: The cable exerts a tension of 2 kN on the fixed bracket at A 1. Determine the vector-component form of the 2-kN force. A. -1.84i + 0.77j + 0.15k C. -1.84i - 0.77j - 0.15k B. -1.84i - 0.77j + 0.15k D. 1.84i - 0.77j + 0.15k 2. Calculate the magnitude of the directional angle (degrees) of the force measured from A, parallel to x-axis. A. 67.36 C. 159.93 B. 85.70 D. 123.14 3. Calculate the moment about point O due to the 2-kN force, in kN-m. A. 1.20 C. 3.64 B. 2.75 D. 1.58 Thanks for watching! Comment for questions and suggestions for future lecture in this series.
