    What type of gear is illustrated here? - ProProfs

    What type of gear is illustrated here?

    • Spur Gear

    • Helical Gear

    • Bevel Gear

    • Rack and Pinion

    • Worm Gear

    • Hypoid Gear

    Correct Answer
    A. Helical Gear
    Explanation
    The gear illustrated in the question is a helical gear. This can be determined by observing the shape of the teeth. Helical gears have angled teeth that are cut in a helix shape, which allows for smoother and quieter operation compared to spur gears. The other options, such as bevel gear, rack and pinion, worm gear, and hypoid gear, have different tooth arrangements and shapes that are not depicted in the given illustration.

    • Rack and Pinion

    • Worm Gear

    • Hypoid Gear

    Correct Answer
    A. Bevel Gear
    Explanation
    The gear illustrated in the given image is a bevel gear. Bevel gears are used to transmit power between intersecting shafts and are characterized by their cone-shaped teeth. They are commonly used in applications where the direction of rotation needs to be changed, such as in automotive differentials or power tools.

    What type of gear is illustrated here?

    • Spur Gear

    • Helical Gear

    • Bevel Gear

    • Rack and Pinion

    • Worm Gear

    • Hypoid Gear

    Correct Answer
    A. Worm Gear
    Explanation
    A worm gear is a type of gear that consists of a helical thread (worm) and a gear wheel (worm wheel) meshing together. The illustration in the question shows a gear with a helical thread wrapped around it, indicating that it is a worm gear. Worm gears are commonly used in applications where a high gear ratio is required, such as in conveyor systems and lifting mechanisms. They provide a compact and efficient way to transmit motion and power between non-parallel shafts.

    An idler gear is a gear that will remain still in a gear train while other gears are engaged and turn.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    An idler gear is a gear that is placed between two other gears in a gear train. It does not remain still, but rather rotates freely to transmit motion between the two adjacent gears. The purpose of an idler gear is to change the direction of rotation or adjust the spacing between the other gears. Therefore, the given statement is false.

    Check the boxes to the left of all the options that refer to an initial steps of a programmer in the development a working piece of code.

    • Algorithm

    • Pseudocode

    • Code

    • Flow Chart

    • Process Analysis

    • Identify Variables

    Correct Answer
    A. Algorithm
    Explanation
    The correct answer is "Algorithm". An algorithm is a step-by-step procedure or set of rules for solving a specific problem or accomplishing a specific task. It is the initial step in the development of a working piece of code as it helps in planning and organizing the logical flow of the code before actually writing the code. It defines the problem, identifies the inputs and outputs, and outlines the sequence of steps to be followed to achieve the desired outcome.

    Use the diagram to calculate the gear ratio of the compound gear train.T=TeethTa=20; Tb=50; Td=75;Te=26; Tf=65 - ProProfs

    Use the diagram to calculate the gear ratio of the compound gear train.T=TeethTa=20; Tb=50; Td=75;Te=26; Tf=65

    • 25:1

    • 16:1

    • 20:1

    • 7:1

    Correct Answer
    A. 7:1
    Explanation
    The gear ratio of a compound gear train is calculated by multiplying the individual gear ratios of each pair of gears in the train. In this case, the gear ratio can be calculated as follows:

    Gear ratio = (Te/Ta) * (Td/Tb) * (Tf/Te)
    = (26/20) * (75/50) * (65/26)
    = 1.3 * 1.5 * 2.5
    = 4.875

    Since the gear ratio is not exactly equal to any of the given options, the closest option is 7:1.

    Check all that can be used in calculating a speed ratio for a gear train?

    • Length of teeth of drivers and length of teeth of drivens.

    • Radius of drivers and radius of drivens.

    • Teeth of drivers and teeth of drivens

    • Rotations of drivers (deg) and rotations of drivens (deg)

    • Speed of drivers (rpm) and speed of drivens (rpm).

    Correct Answer(s)
    A. Radius of drivers and radius of drivens.
    A. Teeth of drivers and teeth of drivens
    A. Rotations of drivers (deg) and rotations of drivens (deg)
    A. Speed of drivers (rpm) and speed of drivens (rpm).
    Explanation
    The speed ratio of a gear train can be calculated using the radius of drivers and radius of drivens, teeth of drivers and teeth of drivens, rotations of drivers (deg) and rotations of drivens (deg), and speed of drivers (rpm) and speed of drivens (rpm). These factors are all related to the gear sizes and rotations, which determine the speed and torque transmission in a gear train. The length of teeth of drivers and length of teeth of drivens is not relevant for calculating the speed ratio.
