For the two-dimensional computational domain of Fig, with the given node distribution, sketch a simple structured grid using four-sided cells and sketch a simple unstructured polyhedral grid using at least one of each: 3-sided, 4-sided, and 5-sided cells. Try to avoid large skewness. Compare the cell count for each case and discuss your results.

- Here we have a very simple one dimensional model of a stroke rehabili- tation patient supported by a robot. Often, when you have a controlled electromechanical system like a robot and a human working together, you want to separate them by a compliant mechanism (spring with stiffness k) so that the robot has some "give". Otherwise, if there are errors in the control of the robot it can be very uncomfortable for a patient. The spring has zero force when x, = xp = 0. The patient provides viscous damping with damping Xp coefficient c. Fp + C Patient mp k Xp Robot Arm Xr Figure 2: Schematic diagram of a very simplified model of a patient pushing against a robot. The robot supports the patient via a spring for safety. In this case we want to eventually determine the force that the patient is exerting on the robot as a function of time, so we'll do some steps towards that goal.

- hi ive have nearly completed this model but i am stuck on a couple last parts. Firstly, the holes on the top need to be placed 30 degrees from the y axis as shown in the handout but also the middle part is meant to have triangular "supports" rather than rectangular and im not sure how to cut them down. This is in autodesk inventor but any help here would be appreciated Once again just the top holes being moved 30 degrees and the support being cut down to the triangular shape shown in the handoutarrow_forwardDon't Use Chat GPT Will Upvote And Give Handwritten Solution Pleasearrow_forwardPls help with Dynamics Homeworkarrow_forward
