Chapter 6Automotive Measurement and Math1. A TORQUE WRENCH is used to apply aspecific amount of turning force to afastener.2. A VACUUM GAUGE is commonly usedto measure negative pressure or suction.
Torque Wrench TheoryOne foot-pound equals one pound of pull on aone-foot-long lever arm
Flex Bar Torque WrenchUses a bending metal beam to make thepointer read torque on the scale
Dial Indicator Torque WrenchVery accurate type of torque wrench
Ratcheting Torque WrenchTorque value is set by turning the handle–fastener is tightened until it clicks
Vacuum TestConnect a vacuum gauge to the inlet the negative pressure side of the pump
Chapter 6Automotive Measurement and Math3. A MICROMETER can easily measure toone ten-thousandth of an inch.4. A FEELER GAUGE is used to measuresmall clearances or gaps between parts.
