Lesson 5/Practice Exercise
LESSON 5
PRACTICE EXERCISE
To insure you understand how to use a torque wrench,
complete the following
exercise requirements.
Requirements 1 through 5
consist of practical
application of what you have learned in this lesson.
Requirement 6 consists
of answering questions about material covered in this
lesson.
Requirement 1:
Determining Torque Values
a.
Using the formula F x D = T, determine the torque value for a torque
wrench 2 feet long.
10 lb-force
=
20 lb-force
=
40 lb-force
=
80 lb-force
=
b.
Using the formula F x D = T, determine the torque value for a torque
wrench 1 1/2 feet long.
15 lb-force
=
30 lb-force
=
60 lb-force
=
120 lb-force
=
Requirement 2:
Determining Torque Value when the Torque Wrench has been Lengthened.
a.
Using the following formula, determine the actual torque for a torque
wrench 2 feet long and an extension 1 foot long:
Dial reading of 40 ft-lb
=
Dial reading of 53.5 ft-lb
=
89
