News: Rocket Power Your Lazy Boy

Since the days of Archytas, rocket propulsion has been the Holy Grail of aeronautics. Thanks to Galileo's inertia, Newton's laws of motion, and the "father of modern rocketry," Goddard, space is not a complete mystery anymore. Rocket-powered aircrafts have evolved from the first liquid fuel rocket in 1926, to the Soviet R-7 which launched Sputnik, to NASA's Saturn V that propelled Apollo 11 to the moon. Today, even billionaire tourists can enjoy space, like Microsoft's Charles Simonyi and Cir...

How To: Convert numbers in and out of standard form

In this video, we learn how to convert numbers in and out of standard form. Standard form is a useful way of writing down very large numbers and very small numbers. To do this, you will look at the number you have and ignore the zeros that are just at the end. Then, write down the basic numbers. Put a decimal point in this number to make it between one and ten. Now, write down x 10 and put the power for how many places the decimal point moved to get to the new number. This will help you write...

How To: Calculate sums in standard form

When a number is expressed in the form of x multiplied by 10^y such that, x < 10 and y is an integer, the number is said to be in standard form. Standard form of expressing numbers finds its use in scientific and statistical fields. This video demostrates how to express, as well as perform basic mathematical operations namely, addition/subtraction, multiplication and division of numbers in the standard form using four examples/mathematical problems. The first two examples demostrate multiplic...

How To: Perform the Slow Flight maneuver

In this AeroCast episode, UND Aerospace discusses the Slow Flight maneuver as performed in the Piper Warrior (PA-28-161), referencing the procedures and standards outlined in the UND Warrior Standardization Manual. All performance tolerances are based on the performance standards set forth by the FAA Private Pilot Practical Test Standards. Since the most critical phases of flight occur at airspeeds less than cruise, a pilot must always be comfortable with his or her airplane’s handling charac...

How To: Compare 2 distributions with the Z-Score formula

This is a video tutorial in the Education category where you are going to learn how to compare 2 distributions with the Z-Score formula. In this example Doug's class has X bar as 71 and a standard deviation of 4. Corey's class has X bar as 68 and a standard deviation of 11. If both Doug and Corey beat the class average and have the same standard score, will Doug have a lower grade than Corey? If both of them have a standard score of 1.5, then Doug will get 77 marks and Corey will get 84.5 mar...

How To: Find the standard error of the mean

In this video the tutor explains about the standard error of the mean. He starts explaining by drawing the diagram of a distribution and now he takes ten samples from the distribution and starts plotting them. He says that in theory if we do it infinite times then we can obtain the sampling distribution of the sampling mean. For the example he takes the number of samples as 10. Now depending on these values of n we can get different sampling distributions. Now he intends to find the mean of t...

How To: Inspect the bumper damage

In this tutorial, we learn how to inspect bumper damage on a vehicle. On older vehicles, there is a metal absorber filled with fluid, so you would be able to see the amount of damage done. This would be able to tell you how far the bumper went in, and if it hit anything important in the vehicle. In newer vehicles, they are reinforced with a type of Styrofoam on the outside. Just because a vehicle doesn't show damage on the outside, doesn't mean there isn't damage underneath the car. So, alway...

How To: Replace your vehicle's power steering pump

Your vehicle's power steering pump is integral to your car functioning at all. That's because the power steering pump is what provides the hydraulic power for steering. Without it, your car would pretty much go nowhere. Inside the pump, retractable vanes spin, pulling hydraulic fluid in with low pressure and spitting it out at high pressure. Every pump has a pressure relief valve to make sure the pressure is never too high, but still your steering pump may wear out over time.
