need help :how to do problems involving tension apllying newton second law???

OpenStudy (anonymous):

Just treat T as another force (acting in the direction u imagine)

OpenStudy (aravindg):

but in some cases we do t- mg sin alpha othr case mgsin alpha - T Why???

OpenStudy (anonymous):

That's just resolving forces in perpendicular directions....

OpenStudy (aravindg):

????xplain

OpenStudy (anonymous):

It's just the direction...

OpenStudy (anonymous):

try decompose the forces and apply Newton law

OpenStudy (anonymous):

One is in the opposite direction to other...

OpenStudy (aravindg):

can u illustrate with example???

OpenStudy (aravindg):

i will post a picture???k???

OpenStudy (anonymous):

Decompose T1 into two perpendicular forces and equate one to W which is opposite in direction to it and one to T2 and solve

OpenStudy (aravindg):

do this one for me with steps then i will understand

OpenStudy (anonymous):

Go ahead, zakauallah..
