So in this question we have to make the force diagrams for all the four police t1, t2, t3, t4 and then use the equations of equilibrium to find the values of t1, t2, t3 and t4.
00:18
Coming to first, that is t1, the forced diagram becomes, this is a thousand kg, t1 is applied upward whereas downward we have mg.
00:41
Now using the equilibrium we can say that t1 is equals to mg that implies m is 1000 mass multiplied by 3 fall acceleration that is 9 .8.
00:59
So t1 becomes 9800 newton coming to t2.
01:11
This is a pulley t1 is applied downwards whereas these are t2 forces.
01:21
So, using this we can write that 2 t2 is equals to t1 or we can write that t2 is equal to half of t1.
01:33
We have calculated t1 that is half of 9800.
01:38
So this gives that t2 is equals to 4 ,900 newton.
01:44
Let us talk about t3 now.
01:49
Force diagram becomes t2, t3.

Okay, to be specific, the pores are somewhat hair at normal...
