Solution:
The angle between the sling and the load is
So the tension in each sling can be calculated as
Where
M is the mass of the load
The Horizontal reaction on the sling will be inward.
After using the spreader, the new angle between sling and load is , the tension in the sling will be
=
The tension will be same as before in the sling move away through the spreader at an angle more than 90 degree the horizontal force will act opposite and will be outward
Answer: 0.087 inches
Explanation:
This problem can be solved applying the <u>Rule of three</u>, which is a mathematical rule to find out an amount that is with another quantity given in the same relation as other two also known.
In this sense, the actual diameter of the Sun is 1,391,020 km and the actual diameter of the Earth is 12,742 km.
Now, applying the <u>Rule of three:</u>
<u />
Sun 1,391,020 km ------ 9.5 inches
Earth 12,742 km --------- ? inches
Therefore:
If the sun is scaled down to 9.5 inches in diameter, the earth would be about <u>0.087 inches </u>in diameter.
