Stokes Theorem
The Attempt at a Solution
I'm having a tough time "cancelling" out integrals from both sides of an equation (if possible). On the right hand of the equation, we know since it is a closed curve, that Stoke's Theorem applies and we can...

Find height (h) of the water level which can result in failure of dam by tipping it over due to water pressure at U/S of dam. Also draw the free body diagram.
Density of water to be = 1000 kg/m^3 and its specific weight=62.4 lb/ft^3
Hints: The specific weight of concrete is...
Oh wait, would I use the magnification factor equation, set it equal to -2, solve for omega sub f, and then set it equal to 2, then solve for omega sub f again?
Okay awesome! One last thing, I'm having a hard time understanding what to do for part b. When they ask for a range, there's not an equation that comes to mind
I think so. I just have one question. I've been asking different people and they give me different answers. The omega that I find is the angular frequency, right? So if I want natural frequency I just divide that by 2pi?
I guess the real question is, what is the difference between angular and...

Assume that there is a tank on a 200 ft pedestal type support. When full the tank and contents have a weight of 50,000 lbs and it is never drained to a point where the tank and contents have a weight less than 20,000 lbs. Assume the pedestal weight is negligible compared to...

Homework Equations
w = √k/m
w = 2π/P
ƒ = 1/P
The Attempt at a Solution
I feel like I'm so close to the answer, I think it has something to do with the fact that there's a spring and pulley in the system that is throwing my answer off. I have
√k/m = 2π/P
So,
P =...

Hi! I wasn't sure how to ask this, but my team and I are making a manila file folder bridge and we are stuck a specific part. We are looking to get the mass of the members and we decided to get it through multiplying the volume of the member by the density of manila file...
