Single beam UVNis and IR instruments differ in their configurations and specific components. Single beam UVNis instruments use a single beam of light passing through a sample cell, while IR instruments can be  utilizing different methods for analyzing light.

Single beam UVNis (Ultraviolet-Visible-Near-Infrared) instruments and IR (Infrared) instruments are both widely used in spectroscopy for analyzing the interaction of light with matter. However, they differ in their configurations and specific components.

In a typical single beam UVNis instrument, a single beam of light passes through a sample cell containing the substance to be analyzed. The light beam is split into two paths: the sample beam that passes through the sample cell and the reference beam that bypasses the sample. The intensity of both beams is measured separately by a detector, and the ratio of their intensities is used to determine the absorption or transmission of light by the sample. This configuration allows for accurate measurement of the sample's optical properties.

On the other hand, IR instruments can be either dispersive or Fourier transform (FT) instruments. Dispersive IR instruments use a prism or a diffraction grating to disperse the infrared light into its different wavelengths. The dispersed light is then detected by a detector array, and the resulting spectrum is used for analysis.

FT-IR instruments, on the other hand, use an interferometer to measure the interference pattern produced by combining the sample and reference beams. This pattern is then mathematically transformed into a spectrum using a Fourier transformation. FT-IR instruments offer advantages such as higher spectral resolution and faster data acquisition.

In terms of specific components, single beam UVNis instruments typically consist of a light source (such as a lamp), a monochromator for selecting specific wavelengths, a sample cell, a detector, and a data analysis system. IR instruments, whether dispersive or FT, also include a source (such as a globar or a laser), an interferometer (for FT-IR instruments), a detector, and a data analysis system.

However, FT-IR instruments additionally require a beam splitter and a mirror for generating the interference pattern.

The given statement is false because Marin factors do not reduce the strength and stress concentrations factors do not increase the stress. Instead, they both reduce the safety factor.

Marin factor is a corrosion factor that takes into account the corrosion of the material of interest. When compared to the yield strength of the material, corrosion usually reduces the yield strength of the material. Because of this, the engineering process must consider the effect of corrosion on the material being used to ensure that it does not become so degraded that it fails prematurely. Hence, the Marin factor increases the safety factor and hence reduces the likelihood of failure.

When there is a change in section or a flaw in a structural member, stress concentration occurs. This is where the stress concentration factor is used. It is used to assess the effect of these conditions on the stress levels that result. The stress concentration factor increases the maximum stress that results in the presence of stress raisers. As a result, it reduces the safety factor and makes it more likely that the structural member will fail prematurely, unlike the Marin factor.

Therefore, the statement is false because the Marin factor reduces the stress and the stress concentration factor increases the stress, and they both reduce the safety factor instead of increasing it.

It is not safe to operate the motor with a 10-hp shaft load.

Explanation :
Solution-
First, determine the rated speed and current of the motor:
Rated speed = 850 r/min
Rated current = 500 V / (0.1414 ohms + 0.0412 ohms + 0.0189 ohms) = 30.22 A
Next, determine the speed and current for a 10-hp shaft load:
Speed = 1700 r/min
Current = 10 hp / (75 hp * 0.902) = 0.1343 A
Finally, determine whether it is safe to operate the motor with the 10-hp shaft load using the magnetization curve. we can see that the current at 1700 r/min is 0.1264 A, which is less than the current for the 10-hp shaft load (0.1343 A).
