Based on the photo provided: Consider the structure shown consisting of a frame member KD [E = 200 GPa, G = 75 GPa] and struts DQ and DC [E = 100 GPa, G = 40 GPa]. The frame member has a rectangular cross-section with width 10 mm and thickness 3 mm while the struts have a circular cross section. For the loading shown, the struts are experiencing an internal compression of 5.8 kN each. Determine: 1) All reaction forces at each support. (Rk_x, Rk_y, Mk) 2)The magnitudes of the internal forces at the midspan of member KD (at section M). (V_m, N_m,M_m) 3.1) The required diameter of struts DQ and DC if their ultimate normal strength is 240 MPa. Determine the diameter considering a factor of safety of 1.25. Express your answer as a whole number. 3.2) Using the answer in 3.1), determine the actual normal stress experienced by struts DQ and DC. 4) Using the answer in 3.1), determine the change in cross-sectional area of the struts DQ and DC. 5.1) The required diameter of the bolts at Q and C if their allowable shear strength is 165 MPa. The allowable strength was determined using a factor of safety of 1.25. Express your answer as a whole number. 5.2) Using your answer in 5.1), determine the actual shear stress experienced by the bolts at Q and C.
