Question

1. an engineer is developing a conveyor belt to help move heavy boxes in factories. the device should be able to move boxes from the first floor to the second floor of a factory. the engineer is building a full - sized model to test her design. write an x to show which questions can be answered by using the model to test the device.

yes no

a. is the motor strong enough to lift the boxes from the first floor to the second floor?

will factory owners be interested in buying and installing the device?

how many boxes can the conveyor belt support at one time?

could a similar design be used to move boxes to the third floor?

a pendulum swings back and forth. at which point does it have the maximum potential energy?

at the bottom of the swing

Explanation:

For the conveyor belt model testing questions:

• A. Is the motor strong enough to lift the boxes from the first floor to the second floor?

Testing the full - sized model can show if the motor has enough power to move boxes between the floors as intended.

• Will factory owners be interested in buying and installing the device?

The model test focuses on the device's functionality, not on factory owners' purchasing interests (which involves market research, not technical testing).

• How many boxes can the conveyor belt support at one time?

By adding boxes to the full - sized model, we can determine the maximum number it can support.

• Could a similar design be used to move boxes to the third floor?

Answer:

yes (X in the "yes" circle for this question)
