The two polythene rods will repel each other. This is because when the rods are rubbed, they acquire a net positive charge which causes them to repel each other since like charges repel.
yes very :)
No. They are powdered metal.
Yes..look up alumaloy welding rods
Connecting rods (con rods) are typically made from either steel or aluminum alloy due to their high strength and stiffness requirements in internal combustion engines. Steel connecting rods are commonly used in high-performance and heavy-duty engines, while aluminum connecting rods are found in lighter-weight and more fuel-efficient applications.
The polythene rods will repel each other due to the transfer of electrons during the rubbing process. Both rods will become negatively charged from gaining electrons and like charges repel, causing the rods to push away from each other.
Rust should generally not be an issue in normal indoor household environments. In rooms where uncontrolled moisture and humidity where rust a matter of concern, you can either avoid the problem altogether by using curtain rods made of non-rusting materials such as aluminum, wood, or copper. If iron or steel rods are used, they should be galvanized, zinc-coated, or aluminum coated.
Yes, curtain rods can be recycled, but it depends on the material they are made from. Metal curtain rods, such as those made from aluminum or steel, are typically recyclable at most scrap metal facilities. Wooden curtain rods may not be recyclable through curbside programs but can be repurposed or donated. Always check with your local recycling guidelines to ensure proper disposal.
Antenna is made in China. Frame is a soft pliable plastic and rods are light aluminum of similar thickness as a soda can.
The expansion rate of materials is typically measured by their coefficient of thermal expansion (CTE). Steel has a CTE of approximately 11-13 x 10^-6 /°C, while aluminum has a higher CTE of about 22-24 x 10^-6 /°C. This means that, for a given temperature increase, aluminum will expand roughly twice as much as steel. Consequently, in applications involving temperature changes, aluminum push-rods will experience greater dimensional changes compared to steel push-rods.
In the metallurgy of aluminum, graphite rods are used as electrodes in the electrolysis process to extract aluminum from its ore. Over time, these graphite electrodes degrade due to the harsh operating conditions, which include high temperatures and chemical reactions. Periodic replacement is necessary to maintain efficient production and ensure proper functioning of the electrolysis cells.
Anode rods are used in RV and home hot water heaters. Aluminum tanks are not required to have an anode rod where steel tanks usually are.
