What is used to level the gantries once the MAC is assembled?

A) Hydraulic jacks

B) Leveling screws

C) Shims

D) Laser leveling systems

Final answer:

Answer:

Shims are used to level the gantries once the MAC is assembled.

The correct answer is C) Shims. Shims are used to level the gantries once the MAC (Moving Arms Control) is assembled. Shims are thin, tapered pieces of material that are placed under the base of the gantries to adjust their height and ensure that they are level.

Shims are a common method for leveling structures in engineering and construction. They are often made of metal or plastic and come in various thicknesses. By inserting shims in specific locations, the gantries can be adjusted until they are level and stable.

Other options mentioned in the question, such as hydraulic jacks, leveling screws, and laser leveling systems, may be used in different construction applications but are not typically used to level gantries in the context of a MAC assembly.
