The rigid bar is supported by the two short white spruce wooden posts and a spring. If each of the posts has an unloaded length of 1 m and a cross-sectional area of 600 mm2, and the spring has a stiffness of k = 2 MN>m and an unstretched length of 1.02 m, determine the force in each post after the load is applied to the bar.
