Two weights, A and C, are fixed to a bar, B. Their masses are: A = 60 kg, B = 230 kg,C = 45 kg. B is, in turn, connected to a fixed vertical post by a hinge and a support cableD. The geometry of the system is shown at right. Treat weights A and C as point masses a)What is the tension in support cable D? Be sure to include a detailed freebody diagram to accompany your analysis.b) What is the magnitude of the force provided by the hinge?c) What is the moment of inertia of the A + B + C as a rigid system, for rotationabout the hinge? For analysis, break the beam into a short piece to the left of thehinge, and a separate longer piece to the right of the hinge. If the support cable D on should break,d) what is the angular acceleration of the beam and weights at the moment the cable breaks?e) what is the magnitude of the linear acceleration experienced by each of the weights, A and C, at moment the cable breaks?
The Straw Hat crew on their journey to Laugh Tale Island found a big treasure box (W). Luffy wanted to place the treasure box (W) as shown in the figure. A 100-mm x 300 mm rectangular beam is supported in a horizontal position. At point "A", it is being held by a pin and at "B" by a cable BD inclined 3 vertical to 4 horizontal. Assume all forces are applied to the beam along its central axis. Given that Fcparallel to grain = 10.50 MPa, W = 79 kN and E = 13800 MPa. Neglecting the weight of the beam and cable, determine whether the design is safe. Cable 2.4 m 2.4 m
