The purpose of the sill plate on an exterior wall is to provide a stable base for the wall framing and to transfer the weight of the structure to the foundation.
The purpose of the sill plate in a building's construction is to provide a stable base for the walls to sit on and to transfer the weight of the structure to the foundation.
The purpose of using a streak plate in microbiology experiments is to isolate and separate individual bacterial colonies for further study and identification.
The purpose of the sole plate framing in a building structure is to provide a stable base for the walls and distribute the weight of the structure evenly to the foundation.
The purpose of a sill plate foundation in a building's construction is to provide a stable base for the walls of the structure to sit on and transfer the weight of the building to the ground.
The purpose of forearm plate holds during a workout is to strengthen the muscles in the forearms, improve grip strength, and enhance overall arm endurance.
The purpose of a pour plate is to determine the concentration of bacteria in a sample by counting the number of colonies that grow on the agar plate after incubation. This method allows for both surface and subsurface colonies to be counted, providing a more accurate representation of the bacterial population in the sample.
the purpose of the flex plate is the same as a flywheel. when the starter is engaged, it spins the flex plate, thus hopefully starting the engine.
The purpose is to realize chemical analysis/experiments at microscale.
