Question

Lami's Theorem:
38. If 'O' is at equilibrium then the values of the tension T, and T, are x, y, if 20 N is vertically down.
Then x, y are
60°
1) 20 N 30 N
) 20/3N, 20 N
T1
150°
60
3) 2013N, 20/3N
4) 10 N, 30 N
T2
20N​

Answer 1

Explanation:

We get two equations from equilibrium of O

T

1

cos30-T

2

sin30=20

T

1

sin30=T

2

cos30

Solving these two equations we get T

1

=20

3

N

And T

2

= 20 N
