A rectangular sign on a store has a mass of 100.0 kg, with the center of mass at the center of the rectangle. Leaning against the wall at point C can be treated as a ball and socket joint. At corner D support is provided only in the y direction. Calculate the voltages T1 and T2 in the support cables; the total force supported at C; and the lateral force R supported at D (need free body diagram)

As shown Figure 3, six flexible cables are used to support two weights of 1000 N and 2000 N.Neglect the weight of each cable.(1) Draw free-body diagram of joint B(2) Draw free-body diagram of joint C(3) Find the forces in all the cables

QUESTION 2 A two-bar planar truss structure has the geometry as shown in Figure Q2. A concentrated force P = 200 kN is applied to the truss at joint C, in the direction shown. Member AC is made of steel (E200 GPa) and has cross-sectional area of 1200 mm² while member BC is made of aluminum (E = 70 GPa) with cross-sectional area of 1500 mm². By using point A, B, and C as node 1, 2, and 3, respectively, the nodal coordinates and the elements connectivity are chosen as shown in the following tables: NODAL COORDINATES NODE x (m) 1 2 3 0 6 3 y (m) 0 -2 2 ELEMENT CONNECTIVITY ELEMENT 1st NODE 2nd NODE 1 1 3 2 2 3

- For the frame of the figure:a) Draw up the free-body diagram of the three elements that compose it, for the BCD element, set theequilibrium equations (summation of forces along the longitudinal axis "t" and the perpendicular "n", as well as thesummation of moments at point C). Note: it is not required to evaluate the reactions or the charges on the elements.b) Make a cut at the midpoint between C and D and “CALCUE” the internal loads numerically.
