- With the 315-lb cylindrical part P in its grip, the robotic arm pivots about O through the range-45 ≤ 0 ≤ 45° with the angle at A locked at 120°. Determine and plot (as a function of 0) the moment at O due to the combined effects of the 315-lb part P, the 105-lb weight of member OA (mass center at G₁), and the 35-lb weight of member AB (mass center at G₂). The end grip is included as a part of member AB. The lengths L₁ and L2 are 2.3 ft and 1.6 ft, respectively. What is the maximum absolute value of Mo and at what value of 8 does this maximum occur? The moment is positive if counterclockwise, negative if clockwise. After you have the plot, answer the questions. 5 15/01 4 120 G₂ Questions: When 8-35°, Mo= i lb-ft When 8 = -6°, Mo= lb-ft When 8 = 19°, Mo= lb-ft 2 iarrow_forward8.

- Staticsarrow_forwardThe O and A joints are vertical hinges that can support theforce in the three coordinate directions and moment on thex and z axes. The mass of arm OA is 2.00 kg, that of arm AB is 2.50 kg, and tray C is 4.00 kg. The center of mass of each member is at its geometric center.Determine the reaction in O for the configuration shown. (need free body diagram)arrow_forwardThe 12ft pole AC (negligible mass) lies in the y-z plane and forms a 30° angle with the z-axis. The pole is held in place at point C by a ball-and-socket joint. Two cables, BD and BE, are fixed to the pole at point B (these represent two separate cables attached at B). A 110 lb force pulls downward at the end of pole AC in the vertical direction (y-direction). If the distance between B and C along the feet, determine the Reactions at C (ball-and-socket joint) The tension in cables BD and BE.arrow_forward
