Step 1 prepare for the presentation

First, determine your audience: who will attend? How many people will attend?

then define the purpose of the presentation: determine how much information you can present in the time allotted, what you want the audience to learn from your presentation.

Step 2: present the presentation

Strategies to help you do this include the following:

- Presentation of data and facts

- Read quotes from experts

- Contact personal experience

The most important part is spoken language: enthusiasm, clarity, simple presentation… body language: eye contact, facial expressions, walking…use of aids: powerpoint, pictures pictures, graphs…

Step 3: End the presentation

You reinforce the main points you have communicated, you will help the audience remember them, provide materials or gifts, keep in touch with the participants

Hello, today I will introduce you to some bearings that I have learned: ball bearing, straight roller bearing, tapered roller bearing, thrust roller bearing, rolling contact bearing. At first, I don’t know much about the features and functions of these bearings, but when the sellers explained more carefully, I understood them very well. Ball bearings use spherial roller to support axial and radial motion while straight roller bearings use cylindrical to support radial motion. Meanwhile, tapered roller bearings are for supporting radial forces and moderate thrust forces using conical rollers. Thrush roller bearings serves to support thrust motion using barel shaped rollers. A rolling contact bearing is also called an anti-friction bearing due to its low friction characteristic. That’s all I know.

Coupling:

Hello, today I will introduce you to some couplings that I have learned. There are 2 types of coupling: flexible coupling and rigid coupling. A flexible coupling can help reduce noise and unwanted vibrations. A beam coupling is a flexible coupling that are the most common flexible couplings. They are cut in spiral shape and can accommodate several degrees of shaft offset. Rigid couplings align the shafts with each other. They also maximize performance and efficiency.Sleeve-style couplings are the most common rigid couplings. It is used to link the parts together, making the machine structure easy to open and close, reduce dynamic loads, and prevent overload when operating.

First, this stage means that hot liquid material is poured into a container and cooled to make the correct shape.

Secondly, the cast iron is turned on a machine called a lathe.

Next, in this step holes are made using a drill.

After drilling, a surface is covered with paint.

When the paint is dry, the part are bolted together using nuts and bolts.

The final step is inspection. The work is checked carefully to make sure that the part has been made properly.
