Answer:
Hydrostatic Force = 35.28KN
Step-by-step explanation:
To solve this question, let's consider integrating the hydrostatic force from the top of the triangle to the bottom.
Formula for a thin horizontal slice of the triangle the force is;
δF=ρgxwδx
Where w is width of triangle; ρ is density of water and g is acceleration due to gravity
At depth x, the width of the triangle is w=2/3x.
Thus, F = (3,0)∫)ρgxwδx
=(2/3)ρg[(3,0)∫)x²δx]
= integrating, we have;
F = (2/3)ρg[(3³/3) - (0³/3)]
F = (2/5)ρg [27/3] = (2/5)(1000)(9.8)(9) = 35280 N = 35.28 KN
The answer is one solution I think
Answer:
1260
Step-by-step explanation:
Volume of the pyramid = area of its base Multiply by its height
The base of the pyramid is a right angled triangle its legs are 14 and 18
Area triangle = (the length of its base)(the length of its height)
In the right angled triangle its base is one of the two legs of the right angle and its height is the other leg
So area of the base =
The volume =
The answer is no solution because if you multiple the left side it would be the same as the right and that would make the answer 0 which is no solution
