The hoist supports the 125-kg engine. Determine the force the load creates in member DB and inmember FB, which contains the hydraulic cylinder H.AnswerStep 1 of 1(a)We are asked to determine the force the load creates in member DB and in member FB, whichcontains the hydraulic cylinder H.We can simplify the problem by realizing that the members FB and DB are two-forcesmembers.Hence we can write the equations of equilibrium for FBD (refer figure 1)\n Figure: 1 + M g = 0 1226.25 × 3 FFB ( ) × 2 = 0 10 F FB = 1938.87 N 1.94 kNHence the force the load creates in member FB iskN. + F = 0 y 3 1938.87( 10 1226.25 Ey= 0 E = 613.125 N y + F = 0 x\n E 1938.87 1 = 0 x (10 E x 613.125 NNow the equations of equilibrium for(refer figure 2) Figure: 2 + M = 0 C 613.125 × 3 F sin(45 )(1) = 0 BD FBD = 2601.27 N 2.6 kNHence the force the load creates in member DB is kN.
