Client comments on the Mechanical Analysis
The mechanical analysis focuses on the weight balance of the weed whacker, which is important to the users. Here are few comments about the analysis:
- The weed whacker is designed to be used at an inclined angle. Thus the freebody diagram should be analyzed at that assumed angle, not in horizontal.
- Please revise the freebody diagram and indicate the meaning of each location, for example, engine, whacker disc and user’s hand-holding locations, etc. From the current diagram, it is difficult for reader to identify these locations.
- The calculation for the impulse is not clear. Please include a simple diagram for better explaining the concept. Also, please define the notations used in the equations, including theta and alpha.
