A cylindrical aluminum rod with a diameter of 10 mm is subjected to an axial tensile load of 5 kN. A foil strain gauge with the following properties is bonded axially along the surface of the rod: Gauge factor (GF): 2.1 Unstrained resistance: 120.0 Ω Measured change in resistance (ΔR): 0.189 Ω Assume the strain gauge perfectly follows the deformation of the rod.  3. Is the strain value within the elastic range of aluminum (assume yield strain ≈ 0.0025). True or False?判断题

Which of the following trees corresponds to a potential parse of the ambiguous sentence below, with correct syntactic categories? Some diagnostics are provided.

Which of the following sentences contain two non-finite verbs? Select all that apply.

The syntactic head of a phrase is the most important element of a phrase and whose category defines the phrase's [ Select ] exponent movement distribution head . Single words or phrases that form part of a phrase but are not the head are called [ Select ] head complement dependent argument modifier . This classification can be further divided into: 1) [ Select ] arguments modifiers complements dependents heads , which have a closer relationship to the head, and are not easily reordered and 2) [ Select ] arguments complements dependents heads modifiers , which have a much looser connection to the head and can often be reordered with other [ Select ] heads modifiers complements dependents arguments . Consider the concrete example: "a strong cup of coffee" and the following diagnostics. In this example, "cup" is a [ Select ] dependent complement argument head modifier , "of coffee" is a [ Select ] argument dependent complement head modifier , "strong" is a [ Select ] argument modifier complement head dependent , and "a" is a [ Select ] modifier dependent head dependent complement .

Analyze the following sentence: The sentence contains [ Select ] 8 6 5 7 3 4 functional words, [ Select ] 2 3 1 4 5 count nouns, [ Select ] 4 5 2 1 3 mass nouns, and [ Select ] 1 5 2 3 4 adjectives.
