continuing to enjoy your problems / vids. Thanks for your work :)

what is angle alpha?

[@ashishpurohit9138]

Angle alpha is wedge angle

[@rohitmishra7963]

Sir will ALPHA be given ???

I guess I missed to mention it in the question..but it will be 20 degree

Sir, Why can't we consider that when the equilibrium breaks the whole system will move towards the left..?

[@ashishpurohit9138]

Dear Naeem, for the given condition where we want to hold 5000N block, we cannot think so, lets try to simulate one experiment..suppose initially w is zero, so the 5000N weight will fall down and system will move towards right side. Now lets increase W gradually, a condition will arise when 5000N wt will not fall and system will in equilibrium now. this state is known for holding the block. suppose you will keep increasing W, a second state will arise where W will pull the lower wedge towards left and 5000 will lift. , this break point is corresponding to statement of lifting 5000. so movement of system defined from this statement, whether you want to lift 5000 N or hold 5000N. I hope this answer will help you.

@@ashishpurohit9138 yes it surely helped a lot I really appreciate it. Thanks 😊

sir why is my T1 coming out negative ?

[@sudhanshunain4690]

u of the pulley wasnt 0.2 in the end which was used, its 0.25

Sir please explain those equation... How cosα and sinα came

[@joevandas2662]

yeah alpha is kind of important to know
