Part A onstants What is the magnitude Fad of the downward force on section a? Express your answer in terms of the tension T Learning Goal To understand the concept of tension and the relationship between tension and force This problem introduces the concept of tension. The example is a rope, oriented vertically, that is being pulled from both ends. (Figure 1)Let Fu and Fd (with u for up and d for down) represent the magnitude of the forces acting on the top and bottom of the rope, respectively Assume that the rope is massless, so that its weight is negligible compared with the tension. (This is not a ridiculous approximation--modern rope materials such as Kevlar can carry tensions thousands of times greater than the weight of tens of meters of such rope.) Fad Submit nswer Part B Consider the three sections of rope labeled a, b, and c in the figure What is the magnitude of the upward force on section b? Express your answer in terms of the tension T At point 1, a downward force of magnitude Fad acts on section a At point 1, an upward force of magnitude Fbu acts on section b At point 1, the tension in the rope is T1 At point 2, a downward force of magnitude Fbd acts on section b b11 Figure 1 of 1 Submit Request Answer Part C The magnitude of the upward force on c, Fcu, and the magnitude of the downward force on b Fbd, are equal because of which of Newton's laws? 1st 2nd 3rd Submit ns
