2 example of physic question and answer about simple friction mechanism

Hello guys ... welcome to eroniana,

In this post i will share with you some problem and answer that related with friction in classical physic, more precisely ... we will solve some simple friction problem...

Before we start to solve the problem ... i want to thank you for reading this post, and take your time to share it ( if you want haha ) ... and sorry if there are some mistake, exactly with may grammar ( i'm still learning...haha)

ok ... with out wating time lets start the first question :

...---...---...---...---...---...---...---...---...---...---...---...---...---...---...---...---...---...---...---...---...---...---...---

First Problem :

          For the first problem a box filled with amount of sand, pulled out with maximum tension of T = 1100 N ... if the floor is rough, find the angle will be fit with maximum tension...

to solve this problem lets describe the force that work at the box :

after we get the acceleration (a) next we derrive a with the change of angle, and set it to zero ... this thing happen when we take the maximum boundry ... and then we can get the angle that we want...



Second Problem :

          there are three box connected with pulley's ... the box have it own mass, and system is accelerate to the right ... the question is if we know all of box mass, find the coefficient of friction ...


same as like before, we must defind all of the force that work with tis syestem ... and solve it sparately, and finnaly solve the problem with subtitution :



and finnaly we ger the coefficient of friction...


ok i think that's all that can i share with you, hope it can help you to solve your problem ( exactly solve your home work...haha kidding ), thank you for visit my blog and take a time to read this post, sorry i there are some mistake ... 

just write in comment if there are something that you want to ask...and let's learn together in Eroniana ...see you on the next post    :D
