The magnitude of the tension in the string marked A and B is mathematically given as
A = 52.5 N
<h3>What is the magnitude of the tension in the string marked A?</h3>
Generally, the equation for is mathematically given as
tan=3/8
negative x
negative x
C= tan=1/6
Hence, considering the Horizontal components
74.9cos(9.46) = A*cos(20.6) + B*cos(51.3)
A = 78.9 - 0.668B
Vertical components
74.9*sin(9.46) + Asin(20.6) = Bsin(51.3)
40.07 = 1.015B
B = 39.5 N
In conclusion, Sub the value of B is the equation of A
A = 78.9 - 0.668B
Sub
A = 78.9 - 0.668( 39.5 N)
A = 52.5 N
