Two blocks of masses m1=2kg and m2=5kg hang over a massless pulley as in the figure. A force F=100N acting on the axis of the pulley accelerates the system upward. Find : a) the acceleration of each block b) the tension in the string.

How would this problem be done with the force acting on the axis? that is new to me
yrelhan4
  • yrelhan4
@3psilon it just means the system is pulled by a force upwards, i guess.
3psilon
  • 3psilon
ok let me fool around with it and I'll see if I get that answer
yrelhan4
  • yrelhan4
right!

So usually in an Atwell problem like this the acceleration is the same right? But I guess that force changes the acceleration of both?
yrelhan4
  • yrelhan4
yes.. acceleration of both the blocks without the force is 30/7 m/s2 .. if that could help..

Actually, this problem is simpler than an Atwood machine. Since the pulley is massless, it is very easy to find the tension in the string, and the accelerations of M1 and M2.

what about the force on the pulley?
Vincent-Lyon.Fr
  • Vincent-Lyon.Fr
Apply N's 2nd law to the pulley.

the pulley is massless..

If a massless body is accelerating, what will be the net force on it?
yrelhan4
  • yrelhan4
0..

@Vincent-Lyon.Fr what would i get after applying nlm to pulley?
Vincent-Lyon.Fr
  • Vincent-Lyon.Fr
Tension in the string... and the problem is done.
yrelhan4
  • yrelhan4
i'll try .. i think i got it somewhat..
