Question b 2.5 m. B 2 m PROBLEM 3.24 A precast concrete wall section is temporarily held by two cables as shown. Knowing that the tension in cable BD is 900 N, determine the moment about Point O of the force exerted by the cable at B. D 2 m Steps: You can do it! Follow the steps that we always follow. Mo (1200 Nm)i- (1500 Nm)j-(900 Nm)k Question 7 m 2.4 m B PROBLEM 3.26 The 6-m boom AB has a fixed end A. A steel cable is stretched from the free end B of the boom to a Point C located on the vertical wall. If the tension in the cable is 2.5 kN, determine the moment about A of the force exerted by the cable at B. You got this! Just keep practicing. MA=(7.89 kNm)j+(4.74 kNm)k
