Domain 1: Earthwork Construction & Soil Mechanics Soil Classification & Properties 1. A soil sample from a job site in Las Vegas has a liquid limit (LL) of 45 and a plasticity index (PI) of 20. According to the Unified Soil Classification System used in Nevada, how is this soil classified? A. A-1-a (Granular) B. A-2-4 (Silty Sand) C. A-4 (Clay) D. A-6 (Organic) Answer: C. A-4 (Clay) Rationale: The Unified Soil Classification System differentiates soils based on their plasticity and gr...

1. What is the primary function of a septic tank within an onsite wastewater treatment system? A) To completely purify the wastewater to drinking water standards B) To separate solids from liquids and promote partial decomposition of organic matter C) To store all wastewater generated by a household indefinitely D) To chlorinate the effluent to kill all bacteria before it enters the soil Answer: B The fundamental role of a septic tank is primary treatment. It receives all raw wastewater ...

A 38-ton air conditioning system is operating with a suction line pressure of 68 psig and a suction line temperature of 50°F. Using a pressure-temperature chart for R-410A, the saturation temperature at 68 psig is approximately 40°F. What is the operating superheat? A. 28°F B. 18°F C. 10°F D. 5°F Correct Answer: C. 10°F Rationale: Superheat is calculated by subtracting the saturation temperature (the temperature at which the refrigerant boils at a given pressure) from the actual...

1. Which satellite orbit remains fixed relative to a specific point on the Earth's equator? A) Low Earth Orbit (LEO) B) Medium Earth Orbit (MEO) C) Geostationary Orbit (GEO) D) Highly Elliptical Orbit (HEO) Answer: C Rationale: A satellite in geostationary orbit (GEO) orbits at an altitude of approximately 35,786 kilometers (22,236 miles) and has an orbital period that matches Earth's rotation. This makes it appear stationary over a fixed point on the equator, which is ideal for ...

1. In the refrigeration cycle, which component is responsible for compressing the refrigerant? A) Condenser B) Compressor C) Evaporator D) Expansion Valve Answer: B Explanation: The compressor acts as the heart of the refrigeration system. It takes in low-pressure, low-temperature refrigerant vapor and mechanically compresses it, which significantly increases both its pressure and temperature. This high-pressure, high-temperature vapor is then pushed to the condenser to begin the heat...
