A bar, AB, with length L = 2 m and with weight Wand is held by two springs (see figure 1.1). The unstressed length of the two spring is the same; the one on the left has a spring constant, k1 = 400 N/m, Q1 %3D while the one on the right has a spring constant, k2 = 200 N/m. At a distance x from A, a load P =1000 N is placed with a vertical and downward direction. W 291N (a) Calculate the distance x at which the bar would rest horizontally at equilibrium. (b) If the two springs were to have different unstressed lengths, show and explain whether it is possible (or not) for the bar to rest horizontally at equilibrium when one spring is stretched while the other spring is compressed. In your own words, state and justify your assumptions and comment on your working. A B ♥P
