Question 4: A machine of 540 kg is bolted at the middle of two parallel simply supported steel beams. The clear span of the beam is 2.4 m. The moment of inertia of the cross-section of each beam is I = 4.2×10¯6 mª. The Young's modulus of the steel is E 200 GPa. When the machine is operating, it will generate a vertical force P(t)=Posinot. When the machine runs at 300 rpm, Po= 1500 N.

A long column such as the one depicted below loaded in compression initially along its axis has a tendency to rotate. Associated with that rotation the load P imparts tipping moments that are resisted by the springs. In the configuration below the springs are connected to the rod with a frictionless slider and remain perpendicular to the rod. The pivot at O is also frictionless, and the masses of the structure are negligible. P k L k (spring) Assume that the springs are at their happy (natural/unstretched) length when 0 = 0. (a) Let the spring constant k, the lengths b, L, and d be given parameters in the problem. Find the load load P as a function of the rotation angle 0 such that the system is in static equilibrium.
