A barge is pulled by two tugboats as
shown in the figure below. The resultant of forces exerted by the tugboats is
1000 kgf. What will be the value of 0 so that tension in rope
2 is minimum?
100 किलोग्राम वजनी एक लिफ्ट एकसमान त्वरण के साथ दो सेकंड में 4 मीटर/सेकंड का ऊपर की ओर वेग प्राप्त कर लेती है। सहायक केबलों में तनाव होगा
300
450
600
0
600
Given :Resultant force exerted = 1000kgf
From free body diagram as shown in figure drawn below,
It is clear that, the increasing value
of 0 , results in decreasing the tension in rope 2, means tension
will be minimum at 0 600 (for the given option)
and maximum at 0 = 00 .
Hence, the correct option is (C).
