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
