Construction Balance Dirt Job Quiz

Balance Dirt Jobs

• A balance dirt job is characterized by having the volume of earth moved balanced, meaning the amount excavated equals the amount needed for fill, minimizing the need for off-site disposal or import.
• Characteristics not associated with a balance dirt job include excess dirt needing disposal or significant import for fill.
• Financial arrangements in a balance dirt job typically involve agreements where the contractor is paid based on the volume of material moved rather than hourly wages.

Time Difference in Construction

• The time difference between the start and end of a through band is termed the "duration" of the construction phase.

Asphalt Application

• Applying low viscosity asphalt to a granular base in preparation for an initial asphalt layer is known as "tack coat" application.

Probability in Testing

• If a test has 6 questions and at least 4 correct answers are required to pass, the probability of passing by guessing involves calculating possible successful combinations of answers.

Committee Formation

• Forming a committee consisting of 4 mathematicians, 3 physicists, and 2 chemists from a larger group requires combinatorial calculations based on available candidates.

Hyperbola Properties

• The eccentricity of a hyperbola with equal transverse and conjugate axes is defined and calculated based on the relationship between these parameters.

Surface Area Increase

• The percentage increase in surface area can be determined through geometric calculations, likely comparing initial and final dimensions.

Spring Deformation

• The velocity of a block at the moment a spring is deformed by 100mm is assessed through principles of dynamics and spring constant calculations.

Curvature Calculations

• The length of the second curve in a compound curve setup would relate to specific geometric properties and lengths associated with the overall path.

Alpha Particle Interaction

• An alpha particle's proximity to a nucleus can be calculated based on nuclear physics principles, explaining interactions at atomic levels.

Block Movement Post-Bullet Exit

• Determining the speed of the block after a bullet exits involves principles of conservation of momentum and kinetic energy calculations.

Inscribed Circle Radius

• The radius of a smaller circle inscribed in a square section with a 4cm radius can be derived from geometric relationships of shapes.

Degree of Curvature

• The degree of curvature for a designed simple curve with a maximum speed of 90kph and limited superelevation can be calculated via engineering standards for roadway design.

Stationing Computation

• The stationing of the P.C.C. for a compound curve requires utilizing specific characteristics and dimensions of the curves involved to ensure proper alignment in construction plans.
