You deserve a medal. I’m basically paying tuition for a course whereas there’s a better teacher online for free
Let the bodies hit the floor LOOOL
Professor Hansen is so fricking good & funny. He's such a gem!
Professor Hanson ,thank for an excellent introduction to Friction Forces. This topic is really the beginning of Engineering Physics One for first year students in science and engineering
"just drive 70 above the bumps" lmao
Love these videos! Keep it up.
Thank you do much, I wish my teachers were Fun and Interactive
Wonderful Statics lessons!! really taking the time to explain the problems along with a good sense of humor :))
Just in time for my final next Friday! Thank you!!
How did it go?
@@parva7152 we will never know...
Ur a legend mate thank u for these vids
Got my bachelor's in 2015, If I could turn back the hands of time, nonetheless I'm still provided with more clarity!!
Love You Professor Hanson THANK YOU SOO MUCH !!
Thank you so much for these
can you add section how to solve cables in your videos? thank you!
Thank you so much
Thank you soooooo much sir for your help and me and friends appreciate your great afer
These videos are awesome thanks a lot
A subscriber and a student from India 🇮🇳
are cos and sin backwards in this? shouldnt the force on the y axis be 100sin30 instead of 100cos30?
wait, 100sin30=100cos60...ok I think i figured it out, I was mixing up reference angles
question here shouldnt it be
So basically, you can just carry the friction variable throughout the calculations until the end, and then give it a positive and negative sign for the minimum and maximum weights.
Why do you break them into components if you tilt the axis? Would they not just be on the x y plane and not need components?
For some of the forces yes, as is the case with W2, the normal force, and the firction force. All three of these are coincident with the new xx axis (W2 and friction) or the new yy axis (normal force). However, the weight of W1 is always vertical, which means that when you tilt the axis it's no longer coincident with yy.
They are always on the Oxy plane, just on different "coordinates" so to speak. That's why you use the components, so that you can sum and subtract these vectors that are at an angle with each other. Don't know if this made sense, or if it's still helpful but yeah :)) good luck!
let the bodies hit the floor awooooga thanks daddy Jeff for your grate videos
I encounter some teaching videos:
they solve the resultant force first before including the friction force
Will the direction of tension change too if the direction of friction opposes.
No, the cable will always be pulling so it will always point in that direction. Cables can not push, they only pull.
hold on, the problem asks to find the weight of w2 to maintain equilibrium, but you calculated the min and max values. so, what is the weight of w2 to maintain equilibrium?
May I know why you are using .35N as the value of friction yet it is given in the question as it's coefficient
Dr. Hanson still #1
Man my professor sucks, discussed friction and moment of inertia in one discussion. The finals was three days later…. Thank youuuuuu. I failed the exams
Georges !
Friction = fun
let the bodies hit the floor
From what I can see, there is not a playlist for statics on your channel? If you have some free time, that would be really helpful! Love the videos!
he does have one :)
7 hours before my final exam
:( wish me luck
what about exam
@@arift.dogan.youtube i got A+ ;)
Oau student
Why is the y component 100cos30 instead od sin30?
Rotated axis
4:26 and the answer is depending on the angle of your legs with the floor, and lets be honest at the picture youe draw legs are at an angle thats not 90, so there is a reaction by the friction in the horizontal direction. If that wasn't the case your drawing will need to take some gymnastic lessons
