Question

Accepted Answer

Questions related to mechanical engineering concepts such as valves, couplings, pumps, gears, and measurement tools.

Valve is a device used to control the flow of fluids. Types include gate, globe, ball, and butterfly valves.
Coupling is a device used to connect two shafts together. Types include rigid, flexible, and fluid couplings.
Pump is a device used to move fluids. Types include centrifugal, positive displacement, and axial flow pumps.
Backlash is the amount of play between two mating gears. It can cause inaccuracies in motion control.
Gears are mechanical components used to transmit power and motion. Types include spur, helical, bevel, and worm gears.
Least count is the smallest measurement that can be read on a measuring tool. Vernier and micrometer have different least counts.
Centrifugal pump is a type of pump that uses centrifugal force to move fluids.
Conveyor is a mechanical device used to transport materials from one location to another.
