Understanding the ASVAB Mechanical Comprehension Test
The ASVAB Mechanical Comprehension test consists of 25 multiple-choice questions, and you have 19 minutes to complete the section. The questions are designed to assess your understanding of mechanical principles, including:
- Simple machines (levers, pulleys, inclined planes, etc.)
- Mechanisms (gears, sprockets, linkages, etc.)
- Physical properties of materials (density, buoyancy, friction, etc.)
Mechanical Comprehension Concepts
To excel in the ASVAB Mechanical Comprehension test, you need to understand the fundamental concepts that govern mechanical systems. Here are some key concepts to focus on:
Simple Machines
Simple machines are devices that change the direction or magnitude of a force. The six types of simple machines are:
- Levers
- Pulleys
- Inclined planes
- Wedges
- Screws
- Wheels and axles
Mechanisms
Mechanisms are systems of connected parts that transmit motion or force. Common mechanisms include:
- Gears
- Sprockets
- Linkages
- Cam-and-follower systems
Physical Properties of Materials
Understanding the physical properties of materials is essential in mechanical comprehension. Key concepts include:
- Density
- Buoyancy
- Friction
- Elasticity
- Strength
Practice Tests and Sample Questions
Practice tests and sample questions are essential to help you gauge your knowledge and identify areas for improvement. Here are some sample questions to get you started:
Sample Question 1
A lever is used to lift a heavy load. If the fulcrum is moved closer to the load, what happens to the effort required to lift the load?
A) Increases B) Decreases C) Remains the same D) Cannot be determined
Answer: B) Decreases
Sample Question 2
A gear train consists of two gears with a ratio of 3:1. If the input gear rotates at 100 rpm, what is the speed of the output gear?
A) 33.3 rpm B) 50 rpm C) 100 rpm D) 300 rpm
Answer: A) 33.3 rpm
