Also,I am still confused about second part. Thanks

Hi! I tried this m2gR - m1gr +mgR =0 I am confused about which forces has torque on this problem? How do I suppose to set up with an equation with both torque and Newton's second law? Thanks!

Hi! I tried Iend for two,so how about this? (2/3)*(5+2)*0.5*0.5 Thanks!

Hi! For first part of my question, I use 1) sin30* N + Fh(Force of hinge) = Mg Fy 2) Fx: T=Ncos30 3) Torque: T*Lsin60 + Mg*Lcos(60) - NL =0 Are these equations right? I am so confused about how to determine the r of the torque (The torque formula is FR but how suppose I...

Homework Statement http://i.imgur.com/vykpq.png Homework Equations The Attempt at a Solution Feel like should use conservative of angular momentum but not sure how to write equations

Homework Statement http://i.imgur.com/oMpaG.png Homework Equations The Attempt at a Solution 1)Friction force always in opposite direction with v? 2)At highest point acceleration is 0? 3)Should larger than because conservative of energy? Thank you

Homework Statement http://i.imgur.com/jL3T9.png Homework Equations Torque = Fr The Attempt at a Solution 1)I write an equation which is Mgsin(theta) - Mg cos(theta)miu = Ma Didn't work 2)Sorry,but I don't understand what slipping means?

Homework Statement http://i.imgur.com/WrwsT.png Homework Equations Torque = FR The Attempt at a Solution 1) I thought I need two torques because they are in oppsite direction 2) I tried use alpha find acceleration and find angular velocity and K=1/2 I omega^2

Hi! Thank you for replies. A) So there are four forces? Mg,Normal force from the wall and floor and Tension, but what about the direction? B) Do I use Parallel Axis Theorm for this quesion? Thanks!

Homework Statement http://imgur.com/MaT4N Homework Equations Torque = Fr The Attempt at a Solution 1) I tried m2 g r - m1 g r = 1/2 M r^2 * (acceleration / r) didn't work 2)I tried replace the moment of inertia equation to above equation,still didn't work
