Before performing maintenance on powered equipment, the FIRST safety step is to:
Answer: Lock out and tag out the energy source
Lockout/tagout isolates and secures energy to protect the worker before service.
A worm gear drive is primarily used to achieve:
Answer: A large speed reduction in a compact space
Worm gears give high reduction ratios and high torque in a small footprint.
Excessive backlash in a gear set means there is:
Answer: Too much clearance between meshing teeth
Backlash is the play between meshing teeth; excess causes lost motion and noise.
Which instrument measures the alignment of a belt drive between two pulleys?
Answer: A straightedge or laser alignment tool
A straightedge or laser checks that both pulley faces lie in the same plane.
A gasket between two flanged surfaces serves to:
Answer: Create a leak-proof seal
Gaskets fill surface imperfections between flanges to prevent fluid or gas leaks.
When a centrifugal pump delivers reduced flow, a common cause is:
Answer: A clogged suction strainer or worn impeller
Blocked suction or a worn impeller reduces the pump's ability to move fluid.
The proper sequence for tightening bolts on a circular flange is:
Answer: A crisscross (star) pattern in stages
A staged crisscross pattern distributes load evenly and prevents flange distortion or leaks.
