A first-class lever has the fulcrum located:
Answer: Between the effort and the load
In a first-class lever like a seesaw, the fulcrum sits between effort and load.
Mechanical advantage in a pulley system is increased by:
Answer: Adding more supporting rope sections
More rope segments supporting the load increase mechanical advantage at the cost of distance.
A dial indicator is used during shaft alignment to measure:
Answer: Runout and small linear deflection
Dial indicators measure tiny movements such as shaft runout and offset.
Which seal type is commonly used to keep lubricant in and contaminants out of a rotating shaft?
Answer: Lip (oil) seal
Lip seals ride against the shaft to retain oil and exclude dirt and water.
If a motor draws excessive current and trips its overload, a likely mechanical cause is:
Answer: A jammed or overloaded driven component
Mechanical binding or overload forces the motor to draw more current and trip protection.
The correct way to remove a press-fit bearing without damaging the shaft is to:
Answer: Use a bearing puller applying force to the inner race
A bearing puller pulls evenly on the inner race to avoid damaging shaft or bearing.
Thermal expansion in a long steel pipe carrying hot fluid is accommodated by:
Answer: Expansion loops or joints
Expansion loops or joints let pipe grow and shrink with temperature without stress damage.
