Final answer:
There is insufficient information to determine the mechanical systems in the scenarios for Cheryl and Tom, making option D correct for both. Jacob is likely dealing with a hydraulic system for a space probe, aligning with option C. The choice of a system is crucial in engineering for problem-solving and understanding physical situations.
Step-by-step explanation:
The scenario presented involves engineers in various situations where they are dealing with mechanical systems. In the case of Cheryl working on her first assignment, Tom diagnosing a ride, and Jacob designing a new space probe, we need to identify the correct mechanical system they're each likely involved with based on the information provided.
For Cheryl and Tom, there is not enough information to accurately determine which type of mechanical system they are working with. The system could be an accumulator, a pneumatic power system, a hydraulic system, or something else entirely. Therefore, option D, Not enough information to determine, is the appropriate match for their scenarios.
For Jacob, who is designing a space probe that needs to move large rocks, a hydraulic system is likely the most appropriate due to its ability to exert large forces which would be necessary for moving large masses; thus, option C, hydraulic system, would be his match.
The choice of a system is an important analytical step in solving problems and thoroughly understanding the situation, as it dictates the approach and the physics laws that apply. This is vital in engineering, where making the appropriate choices can have significant implications for the success of a project.
