Problem I Solve the following problem from the textbook (Use the Varignon Theorem (i.e. Principle of Moments)) Problem 4-5 Problem II Solve the following problem from the textbook. (Use the Varignon Theorem) • Problem 4-8 Problem III For the beam shown in Problem 4-5 of the textbook, determine the resultant moment produced by the forces about a point located 14-ft to the right of point A and at the same level as Point A. (Use the Varignon Theorem). *4-4. Determine the moment about point A of each of the 4 three forces acting on the beam. 4-5. Determine the moment about point B of each of the three forces acting on the beam. F₁ = 375 lb F₂ = 500 lb A B 0.5 ft 8 ft 6 ft 5 ft- 30° F3 = 160 lb Probs. 4-4/5 4-9. I located 4-7. Determine the moment of each of the three forces about point A. *4-8. Determine the moment of each of the three forces about point B. F₁ = 250 N 30° F₂ = 300 N A 60° -2 m- + -3 m- B 4 m 5 3 Probs. 4-7/8 F3 = 500 N
