Are you still able to calculate the % error of the moment inertia? Based on the experimental data in the video, can you calculate the object’s translational acceleration and angular acceleration?

Using Equations 1 through 4, we can derive the following for the measured value of Rotational Inertia:

Procedure:
Watch the videos in the given link.
From Video-1, record the masses and diameters of the cylinder and solid sphere. The diameters of the rings are taken several times since they are relatively flexible objects. Take their average values.
From Video-1, record the length of the inclined plane and the height at two end points to obtain the slope. The heights are measured several times. Take their average value.
From Video-2, for each rolling object, record the travel time from A to B and fill them into the data table. Note that some rolling motions result in the object colliding with the side, or falling off the incline. Do not use that data.

Calculations:
Calculate the average travel time for each object.
Input the average travel time into Equation 6, and calculate the object’s moment of inertia.
Use Equation 5 to calculate the object’s moment of inertia.
Compare the resultant values from steps 2 and 3, and calculate the % error.

QuestionS:
Assuming that a person releases both a solid cylinder and solid sphere from rest at location A, which object do you expect will reach location B first?
If this experiment does not give you mass of the rolling object , are you still able to calculate the % error of the moment inertia?
Based on the experimental data in the video, can you calculate the object’s translational acceleration and angular acceleration?

Develop an evidence-based argument that supports the claim that humans have and continued to gain inspiration from nature in developing and improving flight technology.

Module 1 – A&S Question (PLG1)

Develop an evidence-based argument that supports the claim that humans have and continued to gain inspiration from nature in developing and improving flight technology.

Applying published scientific research along with concepts involved in the evolution of birds, bio-aerial locomotion, and the basic principles of flight, develop an evidence-based argument that supports the claim that frigate birds can stay aloft for months during transoceanic flights.

Explain why a combination of high, hot, and humid conditions creates high density altitude flying conditions. Your explanation should involve a discussion of how air temperature, pressure, humidity affect air density and thus the density altitude.

Finally, read the Forbes Magazine article, The Science Of Why It’s Too Hot For Some Planes To Fly In The Southwest U.S.

After reviewing the information on density altitude, you should understand the importance of air density on the ability of an aircraft to achieve flight and maneuver, and how high density altitude flying conditions – which are typically present on an otherwise “perfect” weather day – are an “invisible” flight hazard that pilots must be aware of during flight planning.

Now, synthesize and apply the information you reviewed on the concept of density altitude to address the following:

Using terms that an average person could easily understand and by applying related concepts and terms, present a practical definition of density altitude.
Fill in the blank: If the value of density altitude is relatively high, the air density is relatively _______.
Of the four main forces acting on aircraft, name the ones that are reduced by high density altitude flying conditions.
Of the four main forces acting on aircraft, name the one that can be altered, in the process of proper flight planning, to reduce the impact of high density altitude flying conditions.
Explain why a combination of high, hot, and humid conditions creates high density altitude flying conditions. Your explanation should involve a discussion of how air temperature, pressure, humidity affect air density and thus the density altitude.
Apply your understanding of density altitude to answer the following scenario-based question:

Explain why a combination of high, hot, and humid conditions creates high density altitude flying conditions. Your explanation should involve a discussion of how air temperature, pressure, humidity affect air density and thus the density altitude.

Module 2 – Focus Topic: Density Altitude (PLG 1)

In this activity, you will focus on the concept of density altitude and its application to the performance of aircraft.

Explain why a combination of high, hot, and humid conditions creates high density altitude flying conditions. Your explanation should involve a discussion of how air temperature, pressure, humidity affect air density and thus the density altitude.
Apply your understanding of density altitude to answer the following scenario-based question:
A general aviation pilot in training is scheduled to do repeated touch and go’s in a Cessna 172 at Bob Adams Field in Steamboat Springs, Colorado on a mid-afternoon in early August. Explain why the aircraft’s ability to take off, land, and climb during the touch and go’s will be negatively impacted. Include an image within your document that visualizes the explanation.

Draw a sketch of this physical system to show where the torques would be. What do you think would be the health advantages or disadvantages of this lifting method?

Mathematical Homework Assignment for Lecture 05
For all your answers,write down your calculations and explain your reasoning. Draw sketches whenever helpful, and please use your units correctly. If you are using any online resources give their URL and webpage title in your answers.
a) You are about to lift a small child off the ground. This child weighs Z pounds. How many newtons of gravitational force downward does this child produce?
b) Use a ruler to measure, to the nearest centimeter, the distance from:
The center of your hand to your elbow. Let’s call this distance r,.
Your elbow to your shoulder. Let’s call this distance r2.
Your shoulder to your lower back . Let’s call this distance r3.
a) If you lift the child up off the ground, you will experience a moment of force — that is, a torque — on the set of joints from your hand to your spine. Draw a simple sketch  of the physical system where you lift the child with your outstretched arms bent over at your waist, and compute the torque at your elbow , at your shoulder, and at your spine.
b) A set of small muscles are attached to your spine at a distance of about 2 inches  from the spine itself. Those muscles must exert force to balance the torque you experience when lifting the child. How much force will those back muscles experience? How many times more force is that than the actual weight of the child?
c) If, rather than bending at the waist with outstretched arms, you instead stand close to the child, bend at the knees, and lift by straightening your legs while keeping your back close to vertical, how much force will those back muscles experience? Draw a sketch of this physical system to show where the torques would be. What do you think would be the health advantages or disadvantages of this lifting method?

[a] A person has a weight at Earth’s surface of Z pounds. What is their mass in kilograms?
[b] If that person jumps six inches into the air, they will add 1.5 joules of potential energy to their body for each kilogram of mass they are. How much potential energy will they add in total if they jump at the bottom of a staircase and land on a higher step 12 inches up?
[c] How much sugar would that person’s body need to metabolize to produce that much energy? You can estimate that stair-jumping is about as efficient as climbing.
[d] A typical fun-size candy bar has, in addition to other ingredients, 10 grams of sugar. How many 12-inch stair-jumps would this person need to do to use up the food energy stored in the sugar of such a candy bar? Does that seem like a reasonable number of stair-jumps to do in a typical exercise session?
