Engineering Concepts and Principles Assessment

The video tutorial covers essential engineering principles, including clearances and tolerances, forces, pressure, friction, velocity, acceleration, work, energy, stress, and strain. It explains how these concepts are foundational to engineering and their applications in design and manufacturing. The tutorial emphasizes the importance of understanding these principles, even when using computer-aided design tools that automate calculations.

What is the primary reason for maintaining clearances in engineering design?

• To increase the weight of the part

• To reduce the cost of materials

• To enhance the color of the part

• To avoid friction or part interference

In engineering terms, what does tolerance refer to?

• The maximum size of a part

• The permissible limit of variations in a part

• The weight limit of a part

• The color variation in a part

Which of the following is a type of force that acts against motion?

• Friction

• Acceleration

• Velocity

• Pressure

How is pressure defined in the context of engineering?

• Force per unit area

• Mass per unit volume

• Speed per unit time

• Energy per unit distance

What distinguishes velocity from speed?

• Velocity is always greater than speed

• Speed includes direction, velocity does not

• Velocity includes direction, speed does not

• Speed is a vector, velocity is not

What is acceleration?

• The distance covered in a given time

• The change in velocity over time

• The force applied to an object

• The speed of an object

What is the relationship between work and force?

• Work is the force applied over speed

• Work is the force applied over mass

• Work is the force applied over time

• Work is the force applied over a distance

How is energy related to work?

• Energy is the opposite of work

• Energy is the capacity to do work

• Energy is the result of work

• Energy is unrelated to work

What does stress refer to in material sciences?

• The force per unit area on a material

• The color change in a material

• The weight of a material

• The change in shape of a material

What happens when the maximum stress of a material is exceeded?

• The material becomes stronger

• The material deforms or fails

• The material becomes lighter

• The material changes color
