Ag. Mechanics 1 / Unit 4.01-4.02

Which leveling instrument is used to sight level lines and measure angles only in the horizontal plane?

• Builder's Level

• Transit Level

• Tripod Level

• Laser Level

What is the primary function of a laser beam level?

• To measure angles in the vertical plane

• To transmit an electronic laser level signal

• To sight level lines

• To adjust tripod legs

What is the first step in setting up a tripod and builder’s level?

• Push tripod legs firmly into the ground

• Loosen the wing nuts and spread tripod legs 3’ to 4’ apart

• Attach instrument to tripod

• Adjust leveling screws

Why should the leveling rod be held straight up?

• To align with the laser beam

• To get an accurate measurement

• To avoid damaging the rod

• To ensure the tripod is steady

What should be checked before and after each reading for accuracy?

• The leveling rod

• The laser receiver unit

• The leveling vial of the level

• The tripod legs

What is the purpose of the 3-4-5 method in construction?

• To measure building height

• To square the corners and obtain dimensions

• To align the leveling rod

• To check the leveling vial

What is the correct diagonal measurement for a building with sides 30' and 40'?

• 55'

• 50'

• 45'

• 60'

What happens if the layout of a building is not square?

• The building will collapse

• The building will not be square, causing construction problems

• The leveling instruments will malfunction

• The diagonal measurements will be equal

What is one method to check if a building is laid out square?

• Ensure the leveling rod is straight

• Check that the two diagonal measurements are equal

• Adjust the leveling screws

• Use a laser beam level

What is an advantage of plans drawn on paper?

• They eliminate the need for leveling instruments

• They are easier to read

• Changes are faster and less expensive to make

• They require less skill to create
