Final answer:
The strength design method is based on the ultimate strength of structural members, making the statement true. The statement about the strength design method, which is based on the ultimate strength of structural members, is true.
Step-by-step explanation:
The statement 'the strength design method is based on the ultimate strength of the structural members' is true.
In structural engineering, the strength design method, also known as the ultimate strength method, focuses on determining the load-carrying capacity of structural members based on their ultimate strength. This method takes into account factors such as material properties, safety factors, and load combinations to ensure that the structure can withstand the maximum expected loads.
For example, when designing a steel beam, the strength design method considers the beam's ultimate strength to determine the appropriate beam size and reinforcement needed to support the applied loads and prevent failure.
The statement about the strength design method, which is based on the ultimate strength of structural members, is true. The claim that high-voltage wires are insulated is false; they are held by insulators but are typically not wrapped in insulating materials. The idea of work function fitting into the classical wave model is also false; it is explained by quantum mechanics.
The statement that the strength design method is based on the ultimate strength of the structural members is true. This method, also known as limit state design, calculates the load-carrying capacity of a structure by taking into account the ultimate strength of its components as well as the various load combinations it may experience throughout its lifecycle. It ensures that the structure will not reach a failure state under the given loads, including safety factors.
The high-voltage wires connected to tall metal-frame towers being held aloft by insulating connectors and wrapped in an insulating material is false. While it is true that insulating connectors hold these wires aloft, the wires themselves are typically uninsulated to prevent excess heat buildup and to save on the cost of insulation material that would otherwise be needed for the long distances these wires cover.
The assertion that the concept of a work function (or binding energy) is permissible under the classical wave model is false. The concept of work function relates to the minimum energy required to remove an electron from the surface of a material and is explained by the photoelectric effect, which cannot be adequately described by classical physics. It is fundamentally a quantum mechanical phenomenon.
