PROBLEM 3.25 3.26 The transformer (as shown) must be lifted vertically out of the pit. Angle = 18°. Determine the required magnitude of force F so that the resultant of the two forces will be vertical. 5000 lb 3.30 Three coplanar conc (a) Calculate the m lies in the line (b) Calculate the a about point O sum. (c) Calculate the inclination (d) Compute th compare w F 0 25° TRAN PROBLEM 3.26 3.27 Refer to the diagram for Problem 3.26. Assume that the trans- former weighs 6000 lb. Determine 0 and the magnitude of the force F so that the resultant of the lifting force (6000 lb) will act vertically upward. 3.28 The plastic barrel tent anchor of Problem 2.8 contains 100 gallons of water. Determine the magnitude and sense of the resultant moment about point O. Be sure to include the weight of the barrel (60 lb) as well as the weight of its contents. F₁ = 75 lb ΟΙ X PROBLE
