Also, What would be the tension in the cables of the cranes? Thankyou
Let the tensions of the cables be T
1 and T
2, corresponding the the crane numbers Crane 1 and Crane 2.
Note I have included units in my working, just a small personal habit.
Using Crane 2 as the pivot,
You can now either say,
or use Crane 1 as a pivot,
Either way, it works out that
So, then tensions on cables of the cranes 1 and 2 are 2,400,000N an 600,000N in that order
hey just a question why is it 0.003 wouldnt it be so ?
30cm
2 is not the same as 30cm x 30cm = (0.3m)^2 = 0.09 m
230cm
2 is the same as 30cm x 1cm = (0.3m) x (0.01m) = 0.003 m
2The general rule is that 1cm
2 = 0.0001m
2
