- The compound beam is supported by a roller at point C, fixed at point A, and the two sections are pinned at point B. It is subjected to a free couple moment M, a distributed load with maximum load intensity w, and a concentrated force F. If the distributed load w = 0.6 kN/m, the concentrated force F = 0.6 kN, and the free couple moment M = 0.8, determine the magnitude of the support reaction (in kN) at pin B. Answer must include 2 places after the decimal point.The sign has a mass of 150kg with center of mass in G. Draw the free body diagram and determine the components along x,y,z of the reaction in ball joint A as well as the tensile strength in wires BC and BD(Caution : they are two different wires). g=9.81m/s²The ideal column is subjected to the force F at its midpoint and the axial load P. Determine the maximum moment in the column at midspan. EI is constant.Hint: Establish the differential equation for deflection, EQ. The general solution is v = C1 sin kx + C2 cos kx - c2x/k2, where c2 = F/2EI, k2 = P/EI
- 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.The rigid frame loaded as shown has pins at support A and D. The connections at B and C are rigid. The frame is loaded with a uniform load (3k/ft) acting on member BC, it has a triangular load (6k/ft) acting on member CD, it has an applied couple of 30 ft-K at point B and a concentrated load of 12K at point C. Determine the reactions and draw the moment diagram. Use Ax as the redundant force reaction. EI is constant.The railcar docklight is supported by the 1 8-in.-diameter pin at A. If the lamp weighs 4 lb, and the extension arm AB has a weight of 0.5 lb>ft, determine the average shear stress in the pin needed to support the lamp. Hint: The shear force in the pin is caused by the couple moment required for equilibrium at A.

If posts AB and CD are to be replaced by those having a material 2, determine the required cross-sectional area of these new posts so that both assemblies deform the same amount when loaded.Assuming the reactions in the support as positive, I planted the sum of forces in x, positive towards the right. For each load, place the "+" or "-" sign as appropriate, or N / A, if the load does not apply in the sum. ΣFx = 0 RAx RAy MA 5 6 7 =0
