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 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 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.
