Explanation / Answer

Since the I-beam is in equilibrium

so net force acting on the I-beam is zero

resolving the tension into components

T is the tension in the cable
same tension exists in both the cables

let theta be the agle between beam top surface and cable

T*sin(theta)+(T*sin(theta))= m*g

2*T*sin(theta) = m*g = 7.4*10^3 N

T = (7.4*10^3)/(2*sin(70)) = 3937.5 N = 3.9*10^3 N
