12.5 Worked Example: 2 Blocks and 2 Pulleys

[@Aryan-hf4wf]

Thank you ma'am, now I know why I always stuck in determining acceleration.
Because I don't know about length constraints.

[@siyaramkumar6337]

Virtual displacement method is quicker I think

[@radreonx5386]

But in the end I got F T and a_1 as unknowns but only had two equations F-2T=m_1a_1 and 3T=2m_2a_1/3 to solve for them! Where did I go wrong?

[@joewwright92]

F is not unknown, its the force you are applying. The unknowns are the tension in the rope and the acceleration, which will depend on the force you are applying.

It's so instructive prob-solving video. Thanks

[@harshitjoshi4561]

Why wasn't the motion of the little block in the middle considered? Or was it just a fixed hinge?

[@vanilla3M]

Yes, I think it is fixed.

[@Aryan-hf4wf]

Ma'am told it's fix , in mid of video. Concentrate

[@saumysharan1358]

Gold nugget thanks a lot

[@pranjalverma3501]

thanks ma'am,good detailed video.

[@siyaramkumar6337]

Thank you very much

mg대신 F가 들어갔다 정도

My first thought when she said "we are going to look at this pulley system" was "why???"

Mam teach something new this type of question we done in 10grade and we have only 2 minutes time
