Problem 1: Using the vector definition M = r x F, determine the moment of the 910-lb force about point O.
Problem 2: Find the moment about point A due to the applied forces as shown below.
Problem 3: What is the sum of the moments exerted on the object?
Problem 4: Determine the resultant of the three couples shown on the block.
Problem 5: Determine the tension in cable AB and AC.
Problem 6: The force F - 90i +60j + 20k acts at the point (0,0, 40). Comport the moment of the force about a line through the origin that has direction cosines (1/√3, 1/√3, 1/√3). (Units are in lb and in.)
Problem 7: To support the tent, the tension in the rope AB must be 40 lb. What are the tensions in the ropes AC, AD, and AE?
Problem 8: Four systems of forces and moments act on an 8-ft beam. Which system are equivalent?
