Three problems misalignment can cause -
correct answer ✅Vibration
Seal Failure
Equipment damage
Define softfoot and what amount is allowable at the coupling -
correct answer ✅The Condition whereby a machine does not sit
properly on all it's feet. And only 0.002" is allowed at the coupling
Runout in regards to alignment is defined as -
correct answer ✅When the shaft and our coupling rotate eccentric
to its axis
Define "Dial Bar Sag" and which dial it affects -
correct answer ✅Dial bar sag is Deflection caused by the length
and weight of our diar bar clamping system, affecting the Rim Dial
vertical reading

inaccurate and must be controlled some how -
correct answer ✅True
Pipe strain is defined as -
correct answer ✅Stress caused by misalignment or poorly
supported piping
T/F The initial sweep readings main purpose are to ensure dial
validity -
correct answer ✅True
After an alignment is completed we should do what with the
jacking bolts -
