With the 400-lb cylindrical part P in its grip, the robotic arm pivots about Othrough the range-45 ≤ 0≤ 45° with the angle at A locked at 120°. Determine and plot (as a function of 8) the moment at O due to the combined effects of the 400-lb part P, the 100-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 2.9 ft and 2.3 ft, respectively. What is the maximum absolute value of Mo and at what value of does this maximum occur? The moment is positive if counterclockwise, negative if clockwise. After you have the plot, answer the questions. 120 lb-ft lb-ft lb-ft Questions: When 9=-31°, Mo= i -771.16 When 0= -6°, Mo= i -1184.98 When 9=33°, Mo= i -1371.81 The maximum absolute value Momax= i 1384.75 lb-ft at 8 = i 25.15
