Answer to Question #255616 in Classical Mechanics for hhhhhh

Question

The m = 10.2 kg block in the figure(Figure 1) is held in place by the massless rope passing over two massless, frictionless pulleys.Find the tensions T1 to T5 and the magnitude of force F? .

Answer 1

$mg=100~N,$

$T_1=mg=100~N,$

$T_1=T_2+T_3=2T_2,$

$T_2=T_3=T_5=\frac{mg}2=50~N,$

$T_4=3T_2=150~N,$

$F=T_5=50~N.$
