Contact surface in rollers

Machines

May 20, 2019

Question

As the friction does not depend upon the surface of contact then how rolling reduces the friction?

Abdur - Pakistan (29046)

Answer

If you consider sliding an object across the ground, you can see that using rollers or wheels results in much less friction.

The only friction in using rollers is due to a slight "stickiness" an the contact surface. But this is negligible.

Question


Hey School for Champions Editors,
I was doing some research on interview tips and noticed that you have this killer resource page on your site: https://www.school-for-champions.com/career/resources.htm#.XOA9-MgzbIU . Awesome job!

Since you’re clearly an authority on the subject, I thought you’d be interested in checking out my article on "Best Interview Practices for Job Seekers". It’s super in-depth and I think it would make an awesome addition to your resource page (especially as your readers would love and benefit from it immensely).

Here’s the link if you’d like to check it out:

Loudness of sound under water

Sound

May 14, 2019

Question

Is the loudness of sound greatest in water than it is in air

Willie - Papua New Guinea (29037)

Answer

The loudness or amplitude of a sound under water seems louder than in air. One reason is that in air, only your eardrum detects the sound. However, under water, your eardrum and your skull sense the sound. Also, sound travels faster under water.

You can test the loudness by comparing a sound from the clicking objects together above water and doing the same under water with your head also under water.

Dropping a piano

Gravity

May 12, 2019

Question

Is there work done on a piano when you drop it from the fourth floor to the ground floor

eman - USA (29032)

Answer

Work is defined as the force required to overcome a resistance times the distance traveled.

Lifting a piano would require work to overcome the force of gravity or weight of the object. Work done by gravity in dropping a piano would be overcoming the slight air resistance.

Hopefully, no one is standing under the piano if dropped from the fourth floor.

Direction of motion

Machines

May 9, 2019

Question

With reference to the explanation given on the second class lever, you said the movement of both load and effort are in the same direction. THIS IS NOT CORRECT. Take an example of a wheelbarrow which in the second class, in it the load (weight) is directed downward while an effort which is applied is directed (acting) upwards, therefore the movements of these forces (load and effort) are opposite.
Thanks,
I'll be glad to get your reaction.

Issa - Tanzania (29029)

Answer

Thank you for your observations. With a wheelbarrow, you pull upward on the handles to raise the load.

I updated the images on Three Lever Classes to clarify the directions on the motions for the various lever classes.

Aging

May 8, 2019

Question

Good Morning,

I hope your Wednesday is going well. My name is Garrett and I’m reaching out on behalf of Baylor University's Online Graduate Programs. I work with the university to distribute useful school-generated content to credible and relevant websites with similar content and audience interests.

Recently, I came across the "Healthy Aging Resources" page on the School for Champions website, located here:
https://www.school-for-champions.com/aging/resources.htm#.XMsVbGhKjIU

I was impressed by the gerontology resources you've assembled and was wondering if you'd be open to sharing an additional resource with your community? 

If so, I’d like to suggest "How Communities Can Prepare for the Growing Aging Population," published by The MPH online program from Baylor University's Robbins College of Health and Human Sciences. This resource discusses how to make communities more inclusive for the older adult population. It offers examples from ten age-friendly U.S. communities and further examines how changes in things like transportation, housing, and outdoor spaces can help people age actively. I believe this would be an excellent resource for your community as it is relevant to the gerontology resources provided on the page.

Below is the URL to the resource:
https://onlinegrad.baylor.edu/resources/communities-safe-aging-in-place/

Would you be open to sharing this resource with your community on the webpage?

Thank you for your consideration. Please feel free to contact me if you have any questions or need additional information. I look forward to hearing from you soon!

Best Regards,
Garrett Perry

Garrett - USA (29027)

Answer

Thanks for the suggested resource. I added a link at Healthy Aging Resources.

Best wishes for success in your work.

Phelelani - South Africa (29024)

Answer

It is good that you are helping and giving him encouragement.

You might let him try out Counting Games for Kids on your computer. The practice can be fun for him and get him more interested in the subject. There are other similar websites to help young students practice.

I hope this helps. Best wishes for your son's success in school.

Computer Science vs Chemical Engineering

Career

April 30, 2019

Question

which of the two can i study to be employed easily: 1.bachelors in computer science. 2.bachelors in chemical engineering.

atuhaire - Uganda (29019)

Answer

There is a demand for college graduates in both areas of study. The most important thing to consider is which are are you most skilled and that you enjoy the type of work.

Note that Computer Science is often used along with Chemical Engineering, so studying both would be good.

It is good to check with companies in your area to see what they have to offer. In this way, you can tell the potential and wages for the type of job you select.

For example, check out:

Computer Programming jobs: http://fresherjobsuganda.com/2018/05/22/graduate-jobs-in-uganda-2018-computer-programmer/

and Chemical Engineering jobs: https://www.engineering.com/jobs/browse-by-country-category/Uganda/Chemical%20Engineering/

I hope that helps. Best wishes for success in your career.

Not part of bicycle

Machines

April 7, 2019

Question

which simple machine is not a part of the bicycle: pulley, lever, screw, or wedge?

fiaz - Guyana (28992)

Answer

You push on the pedals, which is a lever. The bicycle chain forms a pulley. Bicycles have screws to to hold things together. However, I can't think of where a wedge would be used, so a wedge probably is not part of a bicycle.
