- This problem concerns the concept of tension in a rope. Consider a rope subjected to a pulling force on its two ends as shown in (Figure 1). The rope is stationary. An arbitrary point P divides the rope into a left-hand segment L and a right-hand segment R. Figure wi L pull R 232 pull 1 of 3 Part A For segment R and segment L to hold together, they must exert forces on each other. What is the direction of the force exerted on segment R by segment L? View Available Hint(s) left right Submit Part B FLR Assume that segment R exerts a force of magnitude T' on segment L. What is the magnitude FLR of the force exerted on segment R by segment L? Give your answer in terms of T and other constants such as g. ► View Available Hint(s) = Submit % ΑΣΦ www ?A small box of mass m1is sitting on a board of mass m2 and length L (Figure 1). The board rests on a frictionless horizontal surface. The coefficient of static friction between the board and the box is μs. The coefficient of kinetic friction between the board and the box is, as usual, less than μs. Throughout the problem, use g for the magnitude of the free-fall acceleration. Find Fmin, the constant force with the least magnitude that must be applied to the board in order to pull the board out from under the the box (which will then fall off of the opposite end of the board)..pls helppp, I'll rate if you get the correct answer. NOTE: please put all the answers w/o rounding off, even if the answer is long. Ex. 1234.5678910 N
