Guys i need help and some ones please help me Engineering Design:Question 10
Which option describes the engineering design process?
Select one:
1. A series of steps engineers use to identify constraints.
2. A series of steps engineers use to decide which solution is best.
3. A series of steps engineers use to test what they build.
4. A series of steps engineers use to solve problems.

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.

can you make it more obvious. i can't see it properly

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.
