When designing an engineering solution, certain criteria and constraints must be considered. Criteria are the features of the design that must be kept in mind while solving the problem. A criterion answers the question, What do you want the design to do? A constraint is something that prevents the design from performing at its best. These constraints can include time, resources, and money. When designing the airbag, what are some criteria you might consider and what constraints would you anticipate in its implementation?

Create a list of at least two criteria and at least three constraints that you must consider in the design. Rank them in order of importance, with the most important ones at the top of the list.

The criteria that should be considered include:

It should be noted that when designing an engineering solution, there are some criteria and constraints that must be considered in order to achieve the objective of the engineering solution.

Some of the criteria that should be considered include the fact that it should be inflated in the event of a collision, the ability to withstand the impact of the braking force of the occupants, durability, etc.

The constraints listed include how the model design is able to sense a collision that requires the airbag. The possible hazards that can be caused by the gas. Also, it's vital to consider the interaction tendency between the airbag and the occupants of the vehicle.

The criteria listed in order of importance are;

1) To be inflated in the event of a collision in order to protect the occupants of the front of the vehicle

2) To be able to withstand the load of the breaking force of the occupants in the front seat of the vehicle during a collision

3) To be relatively tough so as to resist being torn on impact with a sharp object

The constraints listed in order of importance are;

1) How is the model design able to sense a collision that requires the airbag to be inflated

2) The uncertainty of the load the airbag will withstand upon collision

3) The possible hazard that could be caused by the gas used to inflate the airbag

4) The usage/interaction tendency between the vehicle occupant and the airbag system

Explanation:

In order to produce an effective design, it is important to be able to foresee the possible deficiencies of an idea so as to be able to mitigate the problems before an actual incident happens.

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
