Question

a student argues that a simple hammer is not a technological system because it lacks complexity. how would you evaluate this argument using the five - components model?
correct - hammers only have input and output
incorrect - hammers are tools, not systems
incorrect - the hammer - user combination forms a complete technological system
correct - hammers are too simple to be systems

in a cars cruise control system, what happens when the car starts going uphill and slows down below the set speed?
the system switches to manual control
the system shuts down to prevent damage
the system maintains the same throttle position
the system increases throttle input based on speed feedback

Explanation:

For the first question, a hammer - user combination can be considered a technological system as it has input (user's force), process (transfer of force through the hammer), output (impact on the target), control (user's grip and movement), and feedback (sensation in the user's hand and the result of the impact). So the argument that a hammer is not a technological system due to lack of complexity is incorrect.
For the second question, in a car's cruise - control system, when the car goes uphill and slows down below the set speed, the system uses speed feedback to increase throttle input to maintain the set speed.

Answer:

1. Incorrect - the hammer - user combination forms a complete technological system
2. The system increases throttle input based on speed feedback
