The Russell Traction System To immobilize a fractured femur (the thigh bone), doctors often utilize the Russell traction system illustrated in the figure. Notice that one force is applied directly to the knee, F₁.while two other forces, F₂ and F3 are applied to the foot. The latter two forces combine to give a force F₂ +F3 that is transmitted through the lower leg to the knee. The result is that the knee experiences the total force Ftotal = F₁+F₂+F3. The goal of this traction system is to have P total directly in line with the fractured femur, at an angle of 20.0 above the horizontal.(Figure 1) Find the angle required to produce this alignment of total (Assume the pulleys are ideal.)

In a tug-of-war game on one campus, 15 students pull on a rope at both ends in an effort to displace the central knot to one side or the other. Two students pull with force 196 N each to the right, four students pull with force 98 N each to the left, five students pull with force 62 N each to the left, three students pull with force 150 N each to the right, and one student pulls with force 250 N to the left. Assuming the positive direction to the right, express the net pull on the knot in terms of the unit vector. How big is the net pull on the knot? In what direction?
Determine the magnitude of the y-component of force P (N) if P=104.4 N, Q = 64.4 N , θ= 58.6° and α = 40.97°. Round off only on the final answer expressed in 3 decimal places. Instead of units, indicate the direction of the y-component.
Four pets named Arjay, Baguilat, Cuh-ing, and Dabest play a pulling game with a rope as shown below. Arjay pulls strongly with 610.0 units of force (N). Baguilat pulls with a force of magnitude B = 200.0 N, and Cuh-ing pulls with aforce of magnitude C = 140.0 N. When Dabest pulls on the rope in such a way that his force balances out the resultantof the other three forces, the rope does not move in any direction. With how much force and in what direction mustDabest pull on the rope for the situation to happen? I need help in figuring out is the magnitude of Dabest's pulling force? the direction(use method 1: zero-degree reference line) of Dabest's pulling force and What is the direction(use method 2: geographical direction) of Dabest's pulling force?

A particle, which remains at rest, is acted on by three forces F, G and H. The force F has magnitude 16N and is directed to the right and down, making an angle of 50 degrees with the horizontal. The force G has magnitude 7N and is directed to the left and down, making an angle of 50 degrees with the horizontal. Find the magnitude of the vector H, and the acute angle it makes with the horizontal. Give the magnitude to one decimal place and the angle to the nearest degree.
