None of the above Good Design a. Can be no better than its FRs b. Only applies to what appears on a print c. Should be evaluated by only the number of components d. Is independent of the time required to establish the upper level of the e. Is independent of the time to design f. All of the above decomp osition g. Only a-d aboveh. None of the above A good design decompositio a. Is CEME (collectively exhaustive and mutually exclusive) b. Has parents that equal the sum of the children c. Is an essential part of the des d. Can be developed by zigzagging top down e. Has the minimum number of independent FRs that fulfill the CNs f. All of the above g. Only a-d aboveh. None of the above

Explanation / Answer

Answer of 2)

Constraints means restrictions and limitations.It is used for demarcation of geometrical characteristics so first option is correct that constraint should provide limit.

Design based on constraints uses associated Parameters and links them to attributes of components so constraint must have DPs.

Functional requirements (FRs) essentially specifies something that the system should do.FRs are the statements that identifies a product,design characteristic or constraint hence constraint can relate to several FRs.

Heavy or light Weight and high or low cost would be the requirements of design but constraint is the certain limitations on design i.e the product must be of certain weight and cost must be low,hence cost and weight does not directly influences constraint.
