Otis Elevator Applications Engineer Interview Questions and Answers

To create a detailed AutoCAD drawing for manufacturing, start by defining the dimensions, materials, and tolerances required.

• Start by creating a detailed sketch or concept drawing to plan out the design.

• Use accurate measurements and dimensions to ensure the final product meets specifications.

• Include detailed annotations and notes for manufacturing processes, materials, and finishing requirements.

• Utilize layers in AutoCAD to organize different components of the drawing.

• Conside...read more

The least count of vernier, height gauge, micrometer, digital vernier, and stress strain are important for accurate measurements in engineering applications.

• Vernier caliper: typically has a least count of 0.02 mm

• Height gauge: commonly has a least count of 0.02 mm

• Micrometer: usually has a least count of 0.01 mm

• Digital vernier: often has a least count of 0.01 mm

• Stress strain: does not have a specific least count as it depends on the equipment used

First and third angle projection are methods used in technical drawing to represent a 3D object on a 2D surface.

• First angle projection is commonly used in Europe and Asia, where the object is placed in the first quadrant of the projection plane.

• Third angle projection is commonly used in North America, where the object is placed in the third quadrant of the projection plane.

• In first angle projection, the top view is placed below the front view, while in third angle projection,...read more

AutoCAD header tabs are used to organize and access different functionalities within the software.

• Header tabs are located at the top of the AutoCAD interface.

• Each tab represents a different set of tools or functions.

• Tabs can include options for drawing, editing, annotating, and more.

• Users can easily switch between tabs to access the desired tools.

• Examples of header tabs in AutoCAD include Home, Insert, Annotate, Parametric, and View.

Finishes grades refer to the different levels of surface quality and appearance achieved through various finishing processes.

• Finishes grades are used to classify the quality of surface finishes on materials.

• Common finishes grades include #4, #8, and mirror finishes.

• The grades are determined by factors such as smoothness, reflectivity, and texture.

• Different industries may have specific standards for finishes grades.

• Finishes grades can be achieved through processes like polishi...read more

An elevator is a vertical transportation device that moves people or goods between floors in a building.

• Elevators are powered by electric motors and controlled by buttons or a touch screen panel.

• They use a system of cables, pulleys, and counterweights to move up and down.

• Elevators have safety features such as emergency brakes and sensors to prevent accidents.

• Modern elevators can be equipped with smart technology for energy efficiency and improved user experience.

Types of tolerance include geometric, dimensional, and material tolerance.

• Geometric tolerance: controls the form, profile, orientation, location, and runout of features

• Dimensional tolerance: specifies the acceptable variations in size

• Material tolerance: defines the acceptable variations in material properties

• Examples: positional tolerance, concentricity tolerance, surface finish tolerance
