Answer:

4. A series of steps engineers use to solve problems.

Explanation:

The process of engineering design is a sequence of procedures that engineers pursue to arrive at a solution to a specific problem. Most times the solution includes creating a product such as a computer code, which fulfills certain conditions or performs a function. If the project in-hand includes designing, constructing, and testing it, then engineers probably adopt the design process. Steps of the process include defining the problem, doing background research, specifying requirements, brainstorming solutions, etc.

Why would an aerospace engineer limit the maximum angle of deflection of the control surfaces?

WITCHER [35]

Answer:

You can create high drag which allows a steeper angle without increasing your air speed on landing. you can reduce the length of landing role. Flaps are also used to increase the drag they are retracted when they are not needed. it is adviseable to down he flaps during the time of take off.

Explain the difference between statically determinate beam and statically in determinate beam with sketch.

riadik2000 [5.3K]

Answer

Statically determinate beams are those beams in which the unknown reaction forces are equal or less than the equilibrium equation.

As shown in figure 1 in which reaction forces are 3 and we have 3 equilibrium equation so beam is determinate.

Statically indeterminate beams are those beams in which unknown reaction force are more than the equilibrium equation.

As shown in figure 2 in which reaction forces are 6 and we have 3 equilibrium equation so beam is indeterminate.
