Explanation:
To solve this problem we must draw a free body diagram, where the bird is located, the posts and distances mentioned.
In the attached image we can see the free body diagram with different forces, angles and distances.
By conducting a distance analysis we can find the angles on both sides of the rope relative to the horizontal.
Then we perform a force analysis on the X-axis and the y-axis in order to find the two equations we need to find the stresses in the cables (T1 & T2)
Answer:
The value is
Explanation:
From the question we are told that
The volume of the bottle is
The gauge pressure of the air is
Generally the volume of air before the bottle is turned upside down is
Generally the volume air when the bottle is turned upside-down is
From the the mathematical relation of adiabatic process we have that
Here r is a constant with a value r = 1.4
So
