Textbook Question
Chapter 9.9, Problem 2P
Why would a designer place items (demos of function) in the morphological chart if he or she knows that they would not be feasible?
Expert Solution & Answer
To determine
The purpose of placing items (demos for function) in the morphological chart if he or she knows that they would not be feasible.
Explanation of Solution
In morphological chart every possible solution is placed even though knowing that they might not be feasible to avail those choices whenever a compatible combination is chosen according to a particular theme such as, economy, environment, ergonomics etc..
A compatible solution might not be correct for a particular theme which makes the designer to take all possible combinations into account.
Also every possible combination is represented in morphological chart to identify the solution space of a design problem.
Thus the above discussion states the purpose of placing items (demos for function) in the morphological chart even if he or she knows that they would not be feasible.

This is a tilt and rotation question. Here are notes attached for reference. ONLY UPLOAD A SOLUTION IF YOU ARE SURE ABOUT THE ANSWER PLEASE.
(b): Let us first consider controlling the orbit of deputy spacecraft to rendezvous with chief spacecraft.
Define x = [r] and x = x = R to represent the deputy orbital state and its target (= chief
orbit) in Cartesian coordinates, respectively. The control input is thruster acceleration, u € R³, in the
ECI frame. Denote the relative state by dx = x-x. Table 2 summarize the initial orbital elements.
