Neck Traction
Physics Question-By?
The question is: It is a patient in traction neck and skull has claws, as shown in the diagram below. I must find the maximum value of the sprung mass to not cause tension or other force in the neck, knowing that the mass of the head is 4.2 kg and the coefficient of friction between the bed and his head is 0.2 to this day I Ff = Tx and T = Ty + FG1 + FG2 But I am not sure if this is correct and how to take the following step …. Please help would be greatly appreciated. Diagram: http://s855.photobucket.com/albums/ab116/brittx_17/?action=view¤t=Snapshot2009-11-0810-18-58.png&newest=1
The head is 4.2 kg (4.2 * 9.8) = 41.16 N most can be enforced without moving the head (MU) * (w_head) = 0.2 * N = 8.232 N 41.16 You rightly said that f_f T. = I am not sure of your second equation is because the scheme is not a label with the words you used. The tension in the line would be (mg), the mass flight time of the gravitational constant T: = mg Substituting: T = mg = f_f You also know that cos (15) = 8.232 * N f_f because that's what you can put more force on the head without moving it, and cos (15) gives the horizontal component of tension in the line. Substituting again, then f_f = (8.232 N) / cos (15) = mg = m (8.232 N) / (COS (15) * g), m = 8.232 / (COS (15) * 9.81) = 0869 kilograms
