Question

If we wanted the valves of an engine to remain open for a period of time, what type of function would we need?

A) Step function
B) Linear function
C) Exponential function
D) Periodic function

Answer 1

To keep engine valves open for a specific period of time and ensure regular opening and closing intervals, a Periodic function is required, as it repeats its value in a cyclical manner.

Step-by-step explanation:

In the context of engine mechanics, if we want the valves of an engine to remain open for a specified period of time and then close, we would need a Periodic function. A Periodic function repeats its values at regular intervals or periods, which aligns with the functioning of an engine where the valves must open and close at specific times during the engine cycle. The other functions, such as Step, Linear, and Exponential, do not offer the cyclical pattern necessary for the continual operation of engine valves.
