Saca Mechanical 2 Exam Questions and Answers
What technique should be used when lifting heavy power transmission components? - -
Keep back straight, bending knees, while lifting with legs
-Which of the following is the coupling that would be used to combine two short shafts to
replace a long straight shaft? - -A rigid coupling
-Before removing a machine guard to fix a machine, what step should a maintenance
technician perform? - -Lockout/Tagout the machine
-What tool is used to shorten a roller chain? - -Chain breaker
-Which of the following is not one of the steps required to install an HTD belt? - -Make
sure sprocket centers are at the same distance above the mounting plate
-Which of these conditions does NOT indicate that a V-belt drive sheave needs to be
replaced? - -Top surface of the belt is worn
-Which of the following is the primary function of a lubricant? - -To improve mechanical
efficiency
-Thermal expansion causes the __________ of a rotating component to change, which affects
alignment with other shafts. - -shaft height
-In what way are grid couplings different than chain coupling? - -Grid couplings allow for
more misalignment because they are torsionally more flexible
-Which type of shaft misalignment is corrected first when performing a shaft alignment
procedure? - -Vertical angular
-What component transmits power from a shaft to a timing belt? - -pulley
-Which of the following is an installation procedure that will shorten the life of the belt? - -
Force the belt onto the pulleys
-What method is used to find the nominal length of a conventional, or classic v belt? - -
Measure the inside length of the belt
-A v belt match code is used to: - -Identify belts to be used in a multi belt system
-Which of the following is indicated if high temperature is detected in a pillow block
bearing on a v belt drive? - -belt is too tight
