Problem (2) A uniform slender rod of mass m is released from rest when 0 = 0°. Determine the magnitude of the reactive force exerted on it by pin B when 0 = 90° as a function of mg.

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 5.5-kg uniform rod is pinned at end A. It is also subjected to a couple moment of 50 Nm. The spring is unstretched when 0 = 0, and has a stiffness of k = 60 N/m.

In the figure below, the beam is cantilevered from the wall. The connection of the beam to the wall can be considered a general interaction. The beam has a uniform density, so it will be subject to a weight force applied mid-way between points A and B. length from point A to point B =10.0 meters; weight applied at point B = 1.00 kN; beam weight = 0.500 kN Beam embeded in cwalla cautilever B A What is the magnitude and direction (relative to the x-y coordinate system shown in the upper left portion of the figure) of the horizontal and vertical components of the wall support? horizontal = 0 N, vertical = 1.50 kN O horizontal = 1.50 kN, vertical = 0N O horizonatl = O N, vertical = 1.00 kN O horizontal = ON, verttical = 2.00 kN

For a certain arrangement of two bars carrying only axial forces, the equilibrium and compatibility equations are: Equilibrium: t1+3t2=2kN Compatibility: 2e1 + e2 = 0.1mm There is also a temperature rise of 50oC. Show calculations for the tension in the two bars, where EA=90x103kN and α=12 x10-6 *C for both bars and L1=500mm and L2=400mm.
