Part 2 A Pratt roof truss is loaded as shown. Using the method of joints and the method of sections, determine the force in all members. the force P.624KN 80 kN P kN 60 kN В D H 8 m 60 kN A G---Y. MATHaling.com 6 m 6 m E 6 m 40 kN 100 kN 6 m

Question 4 (Type B): Determine the magnitudes of forces in members BF, DF, and DC using the method of section and identify whether they are in tension (T) or compression (C). A E B F₁ = 100 N 45° 2 m D F₂ = 50 N 2 m F 45°

6. Determine the reactions at pin A and roller D and also the force in each member using the method of joints. 10 kip M 10 ft 10 kip 10 ft C DE BOH 2 kip 15 (1

The slotted arm OA rotates about a fixed axis through O. At the instant under consideration, 0 = 34°, 0 = 43 deg/s, and 0 = 28 deg/s². Determine the magnited of the force F applied by arm OA and the magnitude of the force N applied by the sides of the slot to the 0.6-kg slider B. Neglect all friction, and let L = 0.75 m. The motion occurs in a vertical plane. 0 B m
