Question

find the tension in the diagram​

Answer 1

Explanation:

t-7g sin30=0

or t3-t1-mg=0

t2-t1-mg=0

Answer 2

Answer:

T1 = 70 N, T2 = 70$\sqrt{3}$ N, T3 = 140 N

Explanation:

T1 = 70 N

T3 sin 30 = 70 N

T3 = 70 x 2

T3 = 140 N

T2 = T3 cos 30

T2 = 140 x $\frac{\sqrt{3} }{2}$

T2 = 70$\sqrt{3}$ N
