Recitation A 2.35-kg uniform bar of length 1.30 m is held in a horizontal position by three vertical springs. The two lower springs are compressed and exert upward forces on the bar of magnitude Fl 6.80 N and F2 = 9.50 N, respectively. Find (a) the force F exerted by the top spring on the bar, and (b) the location x of the upper spring that will keep the bar in equilibrium.
