In the given hoist geometry, what is the value of S1?

Explanation:
S1 is found by treating the rope path as the hypotenuse of a right triangle formed by the horizontal projection (S1) and the vertical rise in the hoist geometry. Use the Pythagorean relationship: S1^2 plus the vertical distance squared equals the rope length squared. Solving for S1 gives S1 = sqrt(L^2 − V^2), where L is the rope length and V is the vertical drop shown in the diagram. When you plug in the dimensions provided, this calculation yields 7 feet. That horizontal distance is the one that closes the triangle with the given rope length and vertical dimension. The other numbers would not satisfy the same triangle relation with the shown L and V.
