Engineering Principles, Digital Technology, Information Technology, Aerospace Technology,
Biotechnology, Energy & Power Systems, Manufacturing, Construction, Transportation, and Technical
Problem-Solving | STEM Competition Focus | National TSA Event-Aligned Format
Exam Structure
The TSA National Technology Bowl Top Exam for the 2026/2027 competition cycle features a rigorous,
multi-round question format.
Introduction
This TSA Technology Bowl preparation guide for the 2026/2027 competition year reflects the current
STEM standards, technological innovations, and applied engineering principles central to TSA's mission.
The content emphasizes critical thinking, technical knowledge application, and collaborative
problem-solving within competitive technology education.
Answer Format
All correct answers must be presented in bold and green, followed by concise, technically accurate
explanations referencing current engineering practices, technology standards, and scientific principles.
Questions (50 Total)
1. Which engineering principle states that for every action, there is an equal and opposite reaction?
A. Newton’s First Law of Motion
B. Newton’s Third Law of Motion
C. Bernoulli’s Principle
D. Pascal’s Law
Rationale: Newton’s Third Law explains forces in pairs—e.g., a rocket expels gas downward (action),
and the gas pushes the rocket upward (reaction). This is fundamental in aerospace and mechanical
engineering.
2. In computer science, what does “HTTP” stand for?
A. HyperText Transfer Protocol
B. HyperText Transfer Protocol
, C. High-Tech Text Processing
D. Hyperlink Text Transmission Process
Rationale: HTTP (HyperText Transfer Protocol) is the foundation of data communication on the
World Wide Web, defining how messages are formatted and transmitted between browsers and servers.
3. Which renewable energy source relies on the photovoltaic effect?
A. Wind power
B. Solar power
C. Hydroelectric power
D. Geothermal energy
Rationale: Solar panels use the photovoltaic effect to convert sunlight directly into electricity via
semiconductor materials like silicon. This is a key technology in sustainable energy systems.
4. In biotechnology, CRISPR-Cas9 is primarily used for:
A. Protein synthesis
B. Gene editing
C. DNA replication
D. Cell division
Rationale: CRISPR-Cas9 is a precise gene-editing tool that allows scientists to add, remove, or alter
specific DNA sequences—revolutionizing medicine, agriculture, and genetic research.
5. What type of simple machine is a doorknob?
A. Lever
B. Wheel and axle
C. Pulley
D. Inclined plane
Rationale: A doorknob consists of a wheel (the knob) attached to an axle (the spindle). Rotating the
wheel turns the axle with less force—demonstrating mechanical advantage.
