4) A ring fastened to a beam has two ropes attached. These two ropes exert forces on the ring. F₁ is applied at an angle of 20° from vertical. F2 is applied at an angle of 0° from vertical. It is desired that the combined force on the ring is 1000N straight down. If 8° = 30°, then what are the forces, F₁ and F2, in each rope? F2 8-300 20° F₁

Replace the loading on the frame (Figure 1) by a single resultant force. Suppose that F1 = 150 lb, F2 = 50 lb, and M = 500 lb · ft. measured counterclockwise from the positive x axis 0 = 42.6 Submit Previous Answers Correct Here we learn how to find the direction of the resultant force when the magnitudes and directions of the applied forces are given. Part C Figure 1 of 1 Specify where the resultant's line of action intersects member AB, measured from A. Express your answer in feet to three significant figures. • View Available Hint(s) 2 ft ΑΣφ vec y = ft below A 4 ft M Submit -3 ft 30 * F2 < Return to Assignment Provide Feedback

The figure below shows a bird feeder that weighs 184.7 N. The feeder is supported by a vertical string, which is in turn tied to two strings, each of which is attached to a horizontal branch. The left string makes a 60° angle with the branch, while the right string makes a 30° angle. What is the tension in each string (in N)? 60° 30° Bird food left string N right string N bottom string N

Use the method of PINS to determine the true magnitude and direction of the forces in all the members of the truss shown below
