Calculate the resultant tuming moment on the door. 2 m 30 N 0.5m 40 N 60 N 7 50 N Solution: 27.57 Nm clockwise Figure 2.44 14 2. Compute the support reactions for the beam shown in Figure 2.45. Solutions: Ray = 19.45KN and Ray = 20.25KN 4KN 8KN 2KN/m 6KN 2KN/m 3KN [page] A 3.0m 1.5m 1.0m Ray 1.0m 1.5m Ray Figure 2.45 3. A uniform beam has a mass of 15 kg and rests on two surfaces at points A and B as shown in Figure 2.46. Determine the maximum distance x to which a girl can slowly walk up the beam before it begins to slip. The girl has a mass of 53 kg and walks up the beam with a constant velocity. Solution: x = 1.05m 1.2m 0.5m 3.0m Figure 2.46 4. The members of a truss system are connected to the gusset plate as shown in Figure 2.47. If the forces are concurrent at the point O, determine the magnitude of the forces, Fand 7 for equilibrium. 10KN 304 Solutions: T=15.7 KN and F = 11.35 KN. Figure 2.47 5KN 15 目 5. Determine the resultant force on the body, P in the concurrent force shown in Figure 2.48 using calculation and graphical methods. Solution: 223 N. 750N 300N 450N, 30 700N 30° 450 Figure 2.48
