Situation 1: A flexible cable and rigid boom system is used to lift a load of 65kN at the end of Boom at point C. Points A and B are considered pinned in nature. The allowable shearing stress at all bolts are 250OMPa and the alowable bearing stress at all bolts are 300MPA. Note that the initial position of boom is horizontal and segment A and B are vertical. 1. Determine the Tenslon in each cable. 2. Determine the horizontal reaction at A. 3. Determine the vertical reaction at A. 4. Determine the tensie stress at cable. 5. Determine the tensle stress at threadeu part of cable. 6. Determine the lensle stress at each leg of the turn-buckle. 7. Determine the required diameter of bolt- in detail 2 due to snear sress. Round off your answer to multiple of 2mm. 8. Using the rounded value of diameter uutained in number 7, determine the required thickness of gusset plate due to bearing. 9. Determine the elongation of cable in mm. Use E = 200 GPa. 10. Determine the vertical displacement at D due to Tension alone. 11. If the temperature wil be increased by 50 deg. Celsius, determine the vertical displacement at C. Use a = 13.2 x 10/°C.
