After presentation on last Wednesday, I learned more about assertive presentation style from the internet and other groups' presentations since I lacked the visual concept of the model. I watched the video for the sample presentation but when I put together my own presentation, I thought about simplicity and kept everything very concise to two slides. I realized that i need more visual aspects to easy my speech during my presentation. So hopefully, I will improve on the next presentation.
After class, I did some research on electric braking and how it works. Electric braking is using the similar set up as drum brake. When the electricity is connecting to the conductor wires inside the magnet, brake magnet becomes magnetizes and attract to the drum face. The contract between two surfaces creates the friction and rotate the actuating arm which push the shoes outward against the drum. The drum retards the rotation of the shaft and eventually the outer wheels.
