Answer:
stress = 16.9 MPa
Explanation:
The stress in the cable can be calculated as:
Where F is the force and A is the area. So, the area can be calculated as:
Where r is the radius. Since the radius is half the diameter, the radius is 4.0 mm and the area will be equal to:
Then, replacing the force F by 850 N, and A by 50.24 mm², we get that the stress is equal to:
Therefore, the answer is 16.9 MPa
Explanation:
It is given that,
Mass of Madeleine,
Initial speed of Madeleine, (due east)
Final speed of Madeleine, (due west)
Mass of Buffy,
Final speed of Buffy, (due east)
Let is the Buffy's velocity just before the collision. Using the conservation of linear momentum as :
So, the initial speed of the Buffy just before the collision is 7.13 m/s and it is moving due west. Hence, this is the required solution.
Explanation:
Given data
Velocity v=3 m/s
Water volume flow rate V=590 m³/s
Water elevation z=90 m
Water density p=1000 kg/m³
First we need to determine the energy per unit mass
So
Now the power generation potential is:
