equilibrium position shown. Each spring has an unstretched length of 2 m and a stiffness
constant of k = 300 N/m.
2- Replace the force and couple moment system by a wrench. Determine the position
P(x,y) where the line of action of the wrench intersects the (x,y) plane.
3- Determine the tension in the cable and the horizontal and vertical components of the
