Classify the structures in the Figure. Indicate if stable or unstable. If unstable, indicate the reason. If the structure is stable, indicate if determinate or indeterminate. If indeterminate, specify the degree. hinge hinge Unstable, number of reactions are not sufficient Geometrically unstable stable, determinate Stable, Indeterminate 1°

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.

The aluminum rod BC(G=28 GPa) is bonded to the brass rod AB (G= 37 GPa). Each rod is solid and has a diameter of 14 mm. If Tc=30 Nm and Tg= 50 N m, determine the angle of twist at C. 200 mm Brass B Alumimim 300 mm Tc () The magnitude of the intenal reaction torque from A to B is given as TAB= (10) The magnitude of the internal reaction torque from B to C is given as Tec- (N m) (N.m)
