Choosing a Solvable Subsystem Question 2 The excavator shown consists of a boom (2) that can pivot at its base, and a hydraulic cylinder (3), also connected to the base, which extends to raise the boom. A cylinder (5) extends and contracts to change the orientation of the stick (4) relative to the boom. A cylinder (1) extends and contracts to change the orientation of the bucket (6) relative to the stick. The bucket holds material of large weight, while the masses of all the other members are negligible compared to that weight. All loads act essentially in one plane, so the problem can be modeled in 2D. 5 F 1 4 3 Fill in the blanks by selecting one option from each menu. ab Part 1: Member (1): 5 points ab Part 2: Member (2): 5 points aby Part 3: Member (3): 5 points ab Part 4: Member (4): 5 points ab Part 5: Member (5): 5 points ab Part 6: Member (6): 5 points 30 points 6 Identify two force members: Is (1) a two-force member?

As a reminder, it consists of a boom (2) that can pivot at its base, and a hydraulic cylinder (3), also connected to the base, which extends to raise the boom. A cylinder (5) extends and contracts to change the orientation of the stick (4) relative to the boom. A cylinder (1) extends and contracts to change the orientation of the bucket (6) relative to the stick. The bucket holds material of large weight, while the masses of all the other members are negligible compared to that weight. All loads act essentially in one plane, so the problem can be modeled in 2D. Say you want to find the force exerted by the pin at F in terms of the weight of part (6) directly from a single subsystem. Choose that subsystem by clicking on the part numbers. Click on one or many images. 30 points 1 4 انيا Save 3 of 3 ▼ Submit and Finish
