The rigid and weightless rod AB of length 3-ft and the spring AC of spring constant k at its unstretched length Lo=2ft are connected at A, which is originally at the horizontal position. A vertical load P is then applied at A and A moves to A* at the equilibrium position with the angle of e. Take P= 500 lb = 60° 3ft B 0 A Lo =2ft ???????? wwwwww k ? A P=500lb Q1: Find the extension of the spring. Q2: Find the internal tension force TAC in spring AC. (Hint: Consider the equilibrium of point A*. Follow the 3-step procedure of drawing FBD, listing equations, and finding the solution.) Q3: Find the spring constant k of the spring AC
