This quiz will test your knowledge of tools in the Manufacturing Lab, Safety Rules, and Measurement Skills

• 1.

### Choose the tool represented by the picture below.

• A.

Wood rasp

• B.

Sander

• C.

Block planer

• D.

Steel ruler

C. Block planer
Explanation
The tool represented by the picture is a block planer. A block planer is a woodworking tool used to shape and smooth wood surfaces. It has a flat base and a cutting blade that can be adjusted to remove thin layers of wood. This tool is commonly used for leveling and shaping wooden blocks or boards. It is not a wood rasp, sander, or steel ruler, as they have different functions and designs.

### When working with fractions on a tape measure we always reduce the fraction when possible.  Check which fractions below have not been reduced.

• A.

3/8

• B.

6/8

• C.

4/8

• D.

3/16

B. 6/8
C. 4/8
Explanation
When working with fractions on a tape measure, it is important to reduce the fractions to their simplest form. This makes it easier to read and interpret the measurements. In the given options, the fractions 6/8 and 4/8 have not been reduced. To reduce these fractions, we can divide both the numerator and denominator by their greatest common divisor, which is 2 in this case. Therefore, 6/8 can be reduced to 3/4 and 4/8 can be reduced to 1/2.

### Choose the safety precautions below that should be followed when working with hand tools.

• A.

Always wear eye protection when working with tools or around tools

• B.

Wear closed toed shoes when working with tools

• C.

Always unplug power tools before changing bits or blades

A. Always wear eye protection when working with tools or around tools
B. Wear closed toed shoes when working with tools
C. Always unplug power tools before changing bits or blades
Explanation
The answer is correct because it includes all the necessary safety precautions that should be followed when working with hand tools. Wearing eye protection is important to protect the eyes from flying debris or particles. Wearing closed-toed shoes helps to prevent injuries from falling tools or objects. Unplugging power tools before changing bits or blades is crucial to avoid accidental starts or injuries. Following these precautions helps to ensure the safety of the person working with hand tools.

Rate this question:

• B.

Computer altered design

• C.

Communication aided design

• D.

Computer aided design

D. Computer aided design
Explanation
CAD stands for computer aided design. It refers to the use of computer software and systems to create, modify, analyze, and optimize designs. Google SketchUp is a CAD software program that allows users to create 3D models and designs.

### A mousetrap car has forward propulsion as a result of a spring, a lever, a string, and an axle with wheels.  What type of energy is stored in the spring when you wind the string around the axle which compresses the spring?

• A.

Kinetic energy

• B.

Potenial energy

• C.

Atomic energy

• D.

Mechanical energy

B. Potenial energy
Explanation
When you wind the string around the axle, it creates tension in the spring, causing it to compress. This compression of the spring stores potential energy. Potential energy is the energy that an object possesses due to its position or condition. In this case, the potential energy is stored in the spring and can be released to provide forward propulsion to the mousetrap car when the string is released and the spring decompresses.

Rate this question:

• 6.

### What causes a mousetrap car to stop moving forward?

• A.

The spring

• B.

Friction

• C.

The wheels

• D.

Potential energy

B. Friction
Explanation
Friction causes a mousetrap car to stop moving forward. When the car is in motion, the wheels rub against the surface it is moving on, creating friction. This friction opposes the forward motion of the car, eventually bringing it to a stop. The more friction there is between the wheels and the surface, the faster the car will come to a stop. Therefore, friction plays a crucial role in determining the movement and stopping of a mousetrap car.
