- Q:An aluminum clock pendulum having a period of 1.00 s keeps perfect time at 20 degrees celcius. (A) When placed in a room at a temperature of -5.0 Celcius, will it gain or lose time? (B)How much time will it gain or lose every hour.
- A for a swinging pendulum period T =2pi*√(L/g), where L is length of the pendulum, g=9.8m/s^2; metals shrink when cooled, so period will decrease, number of ticks per hour will increase, the clock will hurry up; B? period at t1°=20C° is T1=2pi*√(L1/g); ? period at t2°=-5C° is T2=2pi*√(L2/g); ? the law of linear extension says L2/L1= 1+s*Δt°, where s=23.1·10-6 (1/К°) is specific linear extension of aluminum, Δt°=t2°-t1°; ? thus T2/T1 =√(L2/L1) = √(1+s*Δt°) =f1/f2, where frequency f1= 1 Hz at 20C° or 3600 ticks per hour, hence frequency at -5C° is f2= f1/√(1+s*Δt°); therefore instead of 3600 ticks per hour the clock will do 3600/√(1+s*Δt°) ticks per hour; thus it will gain 3600*(1/√(1+s*Δt°) –1) = = 3600*(1/√(1 -23.1·10-6 *25°) –1) = 1.04 s/hour;
- Q:Are aluminum sheets suitable for outdoor use?

It has a smooth and shiny appearance, but may have minor imperfections and is not as durable as other finishes. 2. Anodized Finish: Anodizing is an electrochemical process that creates a protective layer on the surface of the aluminum sheet. This finish enhances corrosion resistance, improves durability, and provides a wide range of color options. Anodized finishes can have a matte or glossy appearance. 3. Brushed Finish: This finish is achieved by brushing the aluminum sheet with a fine abrasive material, creating a textured pattern. This finish is commonly used for decorative purposes and provides a unique and attractive appearance. 4. Polished Finish: Polishing the aluminum sheet using abrasive materials creates a smooth and reflective surface. This finish is often used for decorative purposes and gives a high-end, mirror-like appearance to the aluminum. 5. Embossed Finish: Embossing is a process that creates raised or recessed patterns on the surface of the aluminum sheet. This finish is commonly used for decorative purposes, as it adds texture and visual interest to the material. 6. Powder Coated Finish: Powder coating involves applying a dry powder to the aluminum sheet and then curing it under heat. This finish provides a durable and weather-resistant coating, and is available in a wide range of colors and textures. 7. Patterned Finish: Patterned finishes are achieved by imprinting different patterns or designs on the surface of the aluminum sheet. This finish is often used for architectural applications and adds visual interest to the material. These are just a few examples of the different surface finishes available for aluminum sheets. The choice of finish depends on the desired appearance, functionality, and application requirements.

- Q:How do aluminum sheets perform in terms of weldability?
- Aluminum sheets generally have good weldability due to their low melting point and excellent thermal conductivity. Welding aluminum sheets is relatively easy and can be done using various techniques such as TIG (tungsten inert gas) welding, MIG (metal inert gas) welding, or even spot welding. However, there are a few factors that can affect the weldability of aluminum sheets. Firstly, the surface of the aluminum sheet needs to be clean and free from any contaminants such as oil, grease, or oxide layers. These contaminants can negatively impact the quality of the weld. Therefore, proper cleaning and preparation of the surfaces to be welded is crucial. Secondly, aluminum sheets have a high thermal conductivity, which means that heat dissipates quickly. This can make it challenging to control the temperature during the welding process. It is essential to have a skilled and experienced welder who can adjust the welding parameters accordingly to ensure a successful weld. Lastly, aluminum sheets have a high coefficient of thermal expansion, which can lead to distortion or warping during welding. To minimize these issues, techniques such as tack welding or clamping may be employed to hold the sheets in position. In summary, aluminum sheets generally exhibit good weldability due to their low melting point and excellent thermal conductivity. However, proper surface preparation, skilled welding techniques, and careful temperature control are essential to achieve high-quality welds and avoid potential issues like contamination, distortion, or warping.
