The resultant pressure R at a dam is calculated by the formula
Options:
Explanation:
The resultant pressure R acting on a dam is the combined effect of the hydrostatic pressure (P) and the weight of the dam (W). These two forces are perpendicular to each other, and to find the resultant pressure, we use the Pythagorean theorem, which gives R= √P² + W². This formula calculates the vector sum of the two perpendicular forces.
Answer:
The resultant pressure R at a dam is calculated by the formula R= √P² + W².
