Outdoor Survival Challenge Post #19

On April  30, 2015  my class had left the school to go to a nearby forest area for a survival outdoor challenge. We had to build a sort of  shelter that seemed acceptable to use in survival .My  group consisting of Terrell, Brianna, Ben, and Tut had suggested building different types of shelter, but I just went straight to building. Later on  the group stop planning and just went with my plan. We had built an impressive shelter that even got the teacher's approval.

1.       Advantages of Pneumatics over Hydraulics– (write/type the 5 key things from the flashcards here)

ü  Hydraulics means use of pressurized fluids to execute a mechanical task.

ü  Commonly seen hydraulics based equipment types are hydraulic presses, hydraulic hoppers, hydraulic cylinders, and hydraulic rams

ü  In order to affect mechanical motion, pneumatics employs compression of gases, based on the working principles of fluid dynamics in the concept of pressure.

ü  Any equipment employing pneumatics uses an interconnecting set of components: a pneumatic circuit consisting of active components such as gas compressor, transition lines, air tanks, hoses, open atmosphere, and passive components.

ü  Hydraulics present certain advantages over pneumatics, but in a given application, pneumatic powered equipment is more suitable, particularly in industries where the factory units are plumbed for compressed air.

2.       Chapter 18 -  (write/type 3 key things from the flashcards here)

ü  Which technologies apply the concepts of Newton's third law? jet airplanes, fireworks, and recoil guns

ü  What is meant by the term "resistance"? Resistance opposes forward movement.

ü  What is Newton's Third Law? Use it to explain how a rocket engine propels a spacecraft into outer space? Every action has an equal and opposite reaction. Thrusters will propel the spacecraft into outer space by pushing hot gases out a very high velocity. According to Newton's third law, the spacecraft will experience an equal and opposite force, propelling it upward into space. Also, acceleration of the games times their mass equals the acceleration of the rocket times its mass.

3.       Chapter 19 -  (write/type 5 key things from the flashcards here)

ü  Other engineers have tackled the problem of making more efficient cars. What are some new car technologies in development today that are designed to reduce the use of fossil fuels? Hybrid vehicles have both gas engines, and electric motors and batteries, so they can use both energy sources, either one at a time or together. Hybrid vehicles capture energy from braking to generate electricity and charge the batteries. Solar - powered vehicles use photovoltaic (solar) cells.

ü  What is the relationship between volume, temperature, and pressure that is useful for designing engines? Volume, temperature, and pressure are related by the equation "Pressure (P) is proportional to the temperature (T) of the gas, divided by the volume (V) of the chamber. "

ü  Give both an advantage and a disadvantage of a diesel engine over a gasoline engine.

Diesel engines are more powerful, and therefore are used to power trains, cargo ships, and other heavy vehicles. Diesel engine exhaust contains more soot and other particulate pollutants than gasoline engines.

ü  What information would you need to know to determine the force with which the piston pushes the air during the second step of the diesel cycle? P=F/A, therefore F= A x P. You would need to determine the pressure in the chamber and the surface area of the piston.

ü  What is the difference between a gas engine and diesel engine?

The main difference between the two types of engines is in the way that they ignite the gas-air mixture. Gasoline engines take in a mixture of gas and air, compress it, and then ignite it with a spark plug. Diesel engines take in just air, compress it, and then inject fuel into the compressed air. The air is compressed enough to raise its temperature sufficiently so that the injected fuel will ignite it.

4.       Inside the Teenage Brain – (write 3 key facts)

ü  What effect do sleep debts have on the brain?

Some say these sleep debts can have a powerful effect on a teen's ability to learn and retain new material -- especially abstract concepts like physics, math, and calculus.

ü  How does lack of sleep affect the teenage brain?

Sleep affects memory and learning.

ü  What is one of the enduring lessons for parents in the video?

Even though the public perception is about building bigger and better brains, what the research shows is that it's the relationships, it's the connections, it's the people in children's lives who make the biggest difference."

20. Know the difference between wire frame models, surface, and solid models
Wire-frame models are undoubtedly the least complicated when compared to the other two 
categories. In a wire-frame model, all the surfaces of the physical object (including the opposite ends and internal components) are represented through bare lines and arcs. Due to the simple drawing techniques used in wire-frame models, they may not be suitable for complicated projects that require uncompromising realistic effects.
Surface models are more realistic than wire-frame models, but not nearly as much as solid models. Unlike wire-frame models, they are created by merging 3D surfaces instead of bare lines and arcs. A three-dimensional surface is more like a piece of paper that can be placed at various angles to specify different shapes. So basically, in surface modeling, designers join multiple surfaces to give it the desired shape as well as to hide the backgrounds that need not be seen.
Solid models are vastly different from the other two types of models on the ground that they are solid inside. In other words, solid modeling can be referred to as a technique used to combine a number of "solid objects" into a single 3D design. Much like a physical object, a solid model also has additional properties like density, weight and center of gravity because of which it is most preferred choice when it comes to designing prototype of a mechanical product.

Omolola Solaru's post # 8-Technology through the Ages.

Technology: the study of the designed world. Used to solve practical problems and extend human capabilities. Developments in technology are evolutionary, and are often the result of a series of refinements to an idea or basic invention.


Impacts of Technology: are divided into four categories: social (the impact on people), political (the impact on policy and laws), cultural (the impact on human achievement), and economic (the impact on the economy).




Paleolithic Age: the Old Stone Age, occurred between 500,000 BC and 10,000 BC and is marked by improvements to diet and security allowing the population to grow.


Mesolithic Age: the Middle Stone Age, occurred between 10,000 BC and 4,000 BC and is marked by the domestication of animals and agriculture.

Neolithic Age: the New Stone Age, occurred between 4,000 BC and 2,300 BC and is marked by specialization, division of labor, and the use of math and documentation of concepts.

Bronze Age: the architectural period that includes combining copper and tin to produce bronze; occurred between 2,300 BC and 700 BC.


Iron Age: the architectural period marked by the use of iron and steel; occurred between 700 BC and 450 AD.


Middle Ages: the architectural period after the Roman Empire; divided into Early Middle Ages, High Middle Ages, and Late Middle Ages; occurred between 450 AD and 1,400 AD and marked by the development of tools of war.

Renaissance: the architectural period marked by the revival of classical influence and the sharing of ideas; occurred between 1,400 AD and 1,750 AD.


Industrial Age: the architectural period marked by the first use of complex machinery, factories and urbanization, occurring between 1,750 AD and 1,950 AD.


Information Age: the architectural period marked by information sharing, gathering, manipulation, and retrieval; occurred between 1,950 AD and present.

Omolola Solaru post # 7-. Balloon Powered Vehicle Challenge

The project was a failure due certain circumstances. So me and two of my group members used a balloon a tied it up in different areas. And we were able to make it a bit stable . Then we applied duck tape to the center of it , and another area . Where we will apply a straw to make a supporter to keep the vehicle attached to the string. So we used a Popsicle stick as the passenger and we thought poking a hole in the vehicle would work . But it turned out to be a failure.

Omolola Solaru's #6- Reverse Engineering and Discovery

 Reverse engineering can help me become a better problem solver and later on  a better engineer is through many ways. It allows me and helps me to  see the loop holes through certain problematic situations. It trains me how to use whatever I have to  make something amazing with such little resources. This can train me on how objects that don't seem important can be of great importance later on.
