Assignment

Question 1

Before starting any alignment, a lock out is performed to protect personnel from machine starts or roll overs. What is meant by the term “intrinsically safe?”

Answer 1

No component of the system will generate sufficient power or generate a spark with a temperature high enough to ignite an explosive substance or gas

Question 2

Why is it important to stay within the operating temperature range and avoid sudden temperature changes when using laser alignment equipment?

Answer 2

Heat and steam cause beam distortion and inaccurate readings

Sudden temperature changes causes inaccuracies while acclimatizing

Question 3

What is the term used for a reference point that is used to set the final elevations of installed equipment?

Answer 3

Bench mark

Question 4

What is meant by the term plumb?

Answer 4

to align to the vertical

Question 5

What is designed to be used so that no matter what angle the incident ray enters, the refracted ray will leave at exactly at 90°?

Answer 5

Optical square

Question 6

When using a tilting level why is a rough leveling important?

Answer 6

To ensure the coincidence level is within adjustment

Question 7

When using a tilting level what must be adjusted before every shot to ensure accurate reading?

Answer 7

Coincidence level

Question 8

Optical tools equipped with a micrometer attachment that includes a vernier scale can measure to an accuracy of:

Answer 8

0.0001”

Question 9

When placing a tilting level between the backsight and foresight, its position should be;

Answer 9

Equal distance from the backsight and foresight

Question 10

What readings would be at the lowest elevation when using an optical level?

Answer 10

the largest number!!!!

Question 11

When using an optical micrometer, when you shoot a backsight what does this reading tell you?

Answer 11

Elevation from the bench mark to the instrument’s line of sight

Question 12

Which optical instrument has the ability to measure angles of rotation in horizontal and vertical planes?

Answer 12

Theodolite

Theodolite = angles

Question 13

Which attachment is required when performing a bucking-in process with a jig transit?

Answer 13

Precision Lateral Adjustor

Question 14

To obtain the most accurate reading using a rough alignment scale, (Rods) what is done?

Answer 14

Rock the rod slowly back and forth on each side of vertical, take the lowest reading

Question 15

What alignment procedures requires a light source and mirror?

Answer 15

Auto-Collimation

Question 16

What requires two telescopes both focused to infinity, to establish a line of sight which is parallel?

Answer 16

Collimation
2 telescopes
Lightsource

Question 17

When performing a vertical wire alignment, extreme care must be exercised to ensure that the inside micrometer readings are the shortest distance. How is the inside micrometer used?

Answer 17

It’s held against the surface and is swept through an arc, starting out short of the wire and adjusting in one increment segments until continuity is sensed

Question 18

Which tool would be used to reference a machine’s vertical centerline?

Answer 18

Jig Transit

Question 19

When using an optical micrometer, the backsight reading is 5.37’ and the foresight reading is 5.74’. What must be done to level these two points?

Answer 19

Add 0.37’ at the foresight

Back sight = Benchmark “the B’s stay together”

The highest measurement is the lowest elevation, the foresight needs to be raised to be level with back sight.

Question 20

What could be used to ensure the jig transit is in the vertical plane?

Answer 20

Wire and weight held vertically

Question 21

What is done to permanently mark a reference point in concrete?

Answer 21

Install a brass plug and centre punch

Question 22

Which of the following laser alignment designs cannot be used if there is dynamic interruption?

Answer 22

Dual laser/Dual detector
