1.
The ratio of output as compared to input is :
Correct Answer
A. Mechanical Advantage
Explanation
The correct answer is Mechanical Advantage. Mechanical Advantage is a measure of the ratio of the output force or work to the input force or work in a machine. It quantifies the effectiveness of a machine in amplifying or multiplying the input force to produce a larger output force. In other words, it is a measure of how much a machine can multiply force or work. Horse Power and Warp Speed are not relevant to the ratio of output compared to input.

Taking a newly designed car and calculating the fuel mileage based on engine size and vehicle weight under perfect conditions is an example of:
Correct Answer
B. Ideal mechanical advantage
Explanation
Calculating the fuel mileage of a newly designed car based on engine size and vehicle weight under perfect conditions refers to the concept of ideal mechanical advantage. Ideal mechanical advantage is a theoretical value that represents the maximum possible advantage that can be achieved in a mechanical system. In this case, it is the maximum potential fuel mileage that can be achieved by the car under perfect conditions, without taking into account any real-world factors or limitations.
3.
The actual fuel mileage of a newly designed car while being driven under various conditions is an example of:
Correct Answer
C. Actual mechanical advantage
Explanation
The actual fuel mileage of a newly designed car while being driven under various conditions refers to the real or true mechanical advantage that the car provides in terms of fuel efficiency. This is because the actual mechanical advantage represents the ratio of the output force (in this case, fuel mileage) to the input force (the conditions under which the car is driven). Therefore, the actual fuel mileage of the car exemplifies the concept of actual mechanical advantage.
4.
What type of gear is this?
Correct Answer
D. Spur
Explanation
Spur gears are the most common type of gear used in various mechanical systems. They consist of straight teeth that are parallel to the axis of rotation. The teeth of the spur gear mesh together to transmit power and motion between parallel shafts. They are efficient, reliable, and capable of transmitting high torque. Spur gears are commonly found in applications such as automobiles, machinery, and appliances.
5.
What type of gear is this?
Correct Answer
D. Helical Gear
Explanation
A helical gear is a type of gear that has teeth that are cut at an angle to the gear's axis. This angled tooth design allows for smoother and quieter operation compared to other types of gears. The helical gear is commonly used in various applications, including automotive transmissions, industrial machinery, and power tools. It provides high efficiency and can transmit large amounts of power.
6.
What type of gear is this?
Correct Answer
D. Helical Gear
Explanation
A helical gear is a type of gear that has teeth that are cut at an angle, rather than straight across like in a spur gear. This angled tooth design allows for smoother and quieter operation compared to other types of gears. Helical gears are commonly used in applications where high speeds and heavy loads are present, such as in automotive transmissions and industrial machinery.
7.
What type of gear is this?
Correct Answer
D. Helical Gear
Explanation
A helical gear is a type of gear that has angled teeth, which allows for smoother and quieter operation compared to other gear types. The angled teeth also provide a larger contact area, resulting in improved load distribution and higher torque capacity. This type of gear is commonly used in applications that require high precision and efficiency, such as automotive transmissions and industrial machinery.
8.
What type of gear is this?
Correct Answer
D. Helical Gear
Explanation
A helical gear is a type of gear that has teeth that are cut at an angle, creating a helix shape. This design allows for smooth and quiet operation, as the teeth gradually engage and disengage instead of all at once. Helical gears are commonly used in applications where high speeds and heavy loads are involved, such as in automotive transmissions.
9.
What type of gear is this?
Correct Answer
D. Helical Gear
Explanation
A helical gear is a type of gear that has angled teeth. It is commonly used in applications where smooth and quiet operation is required, as the angled teeth allow for gradual engagement and less noise compared to other gear types. This type of gear is often used in automotive transmissions, where it helps to transmit power efficiently and smoothly.
