    Which of the following is lowest resistance grounding on earth?

    • A.

      Sand

    • B.

      Clay

    • C.

      Surface loam soil

    • D.

      Limestone

    Correct Answer
    C. Surface loam soil
    Explanation
    Surface loam soil has the lowest resistance grounding on earth compared to sand, clay, and limestone. Loam soil is a mixture of sand, silt, and clay, which makes it more conductive and less resistant to electrical current flow. Sand has larger particles and poor conductivity, while clay has smaller particles and higher resistance. Limestone is a non-conductive rock, making it the least suitable for grounding. Therefore, surface loam soil is the best option for achieving low resistance grounding.

    The general law of mechanics that stress is directly proportional to strain

    • A.

      Hooke’s law

    • B.

      Boyle’s law

    • C.

      Shearing stress

    • D.

      Elasticity

    Correct Answer
    A. Hooke’s law
    Explanation
    Hooke's law states that the stress applied to a solid material is directly proportional to the strain produced in the material. In other words, when a force is applied to a material, it will deform or stretch in proportion to the force applied. This law is commonly used to describe the behavior of elastic materials, such as springs, where the deformation is reversible and the material returns to its original shape when the force is removed. Therefore, Hooke's law is the correct answer because it directly relates stress and strain, as stated in the question.

      Two force member

    • B.

      One force member

    • C.

      Force member

    • D.

      Zero force member

    Correct Answer
    D. Zero force member
    Explanation
    A zero force member in a truss is a member that does not carry any load. This means that there is no force acting on the member, and it does not contribute to the stability or strength of the truss structure. Zero force members are typically found in trusses where the loads are applied at the joints, and they help to maintain the equilibrium of the forces in the truss.

    The reciprocal of the bulk modulus is compressibility. Compressibility is a measure of how easily a substance can be compressed or squeezed. The bulk modulus is a measure of the resistance of a substance to compression. Therefore, the reciprocal of the bulk modulus, which is 1 divided by the bulk modulus, represents the compressibility of the substance.

    A P 1,000,000 issue of 3%, 15-year bond was sold at 95%. What is the rate of interest of this investment?

    • A.

      3.0%

    • B.

      3.4%

    • C.

      3.7%

    • D.

      4.0%

    Correct Answer
    A. 3.0%
    Explanation
    The rate of interest of this investment is 3.0%. This can be calculated by taking the difference between the face value of the bond (1,000,000) and the amount it was sold for (95% of the face value, which is 950,000). The difference is 50,000. Then, divide the difference by the face value and multiply by 100 to get the percentage. So, (50,000 / 1,000,000) * 100 = 5%. However, since the bond has a 15-year maturity, the rate of interest needs to be divided by the number of years, which is 15. Therefore, 5% / 15 = 0.3333%. Rounding to the nearest tenth, the rate of interest is 3.0%.
