In this discussion, you have the option of answering either of the following questions; however, you are welcome to answer both if you would like. Please respond to at least one of the following discussion topics and submit your post to the discussion forum. Your initial post should be 75-150 words in length. Then, make at least two thoughtful responses to your fellow students' posts.

Question A

A high-school student in your neighborhood is taking physics. They are having problems understanding rotational dynamics.

You, having had physics in college, tell them to think of a bicycle wheel.

Explain to them the principles of rotational dynamics as illustrated by a bicycle wheel and discussed in this week's theory.

Question B

Mammals that depend on being able to run fast have slender lower legs with flesh and muscle concentrated high close to the body.
On the basis of rotational dynamics, explain why this distribution of mass is advantageous. Use the concepts of inertia, energy, momentum, moment of inertia, torque, etc. that you have learned in this class in your answer.

Discuss the contribution of transistors to the development of technology. Also, describe the impact of transistors on the environment and at least one current effort to address this issue. Who do you think should be involved in addressing the environmental impact? Address this from the perspective of a professional engineering technologist, considering the concept of professional responsibility addressed in EE100.
