Aerospace
What is aerospace engineering?
Aerospace engineering is the field of engineering focused on aircraft, spacecraft, and the systems that make them work.
What is civil engineering?
Civil engineering is the field of engineering that deals with designing, building, and maintaining infrastructure and structures such as buildings, roads, bridges, dams, and water systems
What is petroleum engineering?
Petroleum engineering is the field of engineering focused on finding, extracting, and producing oil and natural gas from underground reservoirs.
What are the four main forces acting on an aircraft during flight?
lift, weight, thrust, and drag.
What is biochemical engineering?
Biochemical engineering combines biology, chemistry, and engineering to develop processes that use living cells, enzymes, or biological materials to make useful products such as medicines, vaccines, biofuels, and food ingredients.
What are the four main forces acting on an airplane?
Lift, weight, thrust, and drag
What does a civil engineer do?
Civil engineers plan, design, analyze, and help construct infrastructure while considering safety, cost, materials, and environmental impact.
What is natural gas?
Natural gas is a fossil fuel found underground that is made mostly of methane (CH₄). It can be used for heating, generating electricity, and industrial processes.
How does changing the angle of attack affect an aircraft’s lift?
Increasing the angle of attack generally increases lift up to a certain point. If the angle becomes too large, the airflow separates from the wing and the aircraft can stall, causing lift to decrease significantly.
What is a bioreactor, and what is it used for?
Engineers use it to grow cells or microorganisms and control conditions such as temperature, pH, oxygen, and nutrient levels.
What is weight?
Weight is the force of gravity pulling an aircraft toward Earth.
What is concrete?
Concrete is a construction material made primarily from cement, water, and aggregates such as sand and gravel.
What is a well?
A well is a hole drilled into the Earth to reach underground oil or gas.
Why does an aircraft stall, and what happens aerodynamically during a stall?
angle of attack exceeds the critical angle.
Why is controlling temperature and pH important in a bioreactor?
Cells and microorganisms work best within specific temperature and pH ranges. If conditions become too hot, cold, acidic, or basic, the organisms may grow poorly or die, reducing the amount of desired product.
What is an engine's purpose on an aircraft?
An engine provides thrust to overcome drag and move the aircraft
What is tension?
Tension is a force that pulls or stretches a material.
What does a petroleum engineer do?
Petroleum engineers help determine how to drill, produce, and recover oil and gas efficiently and safely.
How does a swept-wing design improve an aircraft’s performance at high speeds, and what are its disadvantages?
Sweeping the wings backward reduces the component of airflow traveling directly over the wing, which helps delay compressibility effects and shock waves at high speeds.
How would you increase the production of a desired protein using genetically engineered bacteria?
nutrient concentration, temperature, pH, oxygen, and gene expression
Why does an airplane need to move through the air to fly?
Moving through air allows the wings to generate aerodynamic forces, including lift.
What is the basic goal of civil engineering?
The goal is to design and build safe, reliable, durable, and useful infrastructure while considering cost, environmental impact, and the needs of society.
What is water saturation?
Water saturation is the percentage of the pore space occupied by water.
How would you determine the optimum altitude and airspeed for maximum fuel efficiency during a long-distance flight?
Engineers consider engine efficiency, aerodynamic drag, aircraft weight, air density, wind, and altitude.
How would you design and scale up a bioreactor from laboratory scale to industrial scale while maintaining the same production efficiency?
oxygen transfer, mixing, heat transfer, nutrient distribution, cell growth, and energy consumption.
