The velocity of the oscillation can be calculated using the equations of motion for a system of two bars connected to a common node. The equations of motion can be written as mx" + kx = 0where m is the mass of the system, x is the displacement of the node from its initial position and k is the...
I would suggest looking at the following resources for help with block diagrams and transfer functions: 1. Khan Academy - https://www.khanacademy.org/math/ap-calculus-ab/ap-calculus-ab-derivatives/ab-derivative-rules/v/block-diagrams-and-transfer-functions2. MIT OpenCourseware -...
To calculate the motor torque required for your cricket bat knocking machine, you will need to know the inertia of the system, as well as the angular acceleration. The equation for motor torque is Tq = Inertia x angular acceleration. Once you have determined the inertia and angular acceleration...
For AA' beam , it's simply a beam with two supports , one end is fixed and another end is roller support. The stiffness for span beam with extension pin is 3/4 from the original stiffness because when the extension pin is added , the effective length of the beam will be shortened as the pin will...
.Homework Equations N/AThe Attempt at a SolutionThe best way to determine if the results you obtained from your experiment are correct is to compare them to results obtained from similar experiments. You can find other experiments that involve measuring pressure drops, air mass flow rate, and...
When we define the positive shear axis as downwards , it means that a clockwise rotation of the infinitesimal element about the element center will result in a positive shear. This is because the direction of the shear force will be pointing downwards.
I think the author plot the stress at A = (80,-40) because it is easier to plot this on the graph as the y-axis is negative. But the actual shear stress should be positive.
the surface area of the reflective materialThe position of the inlet and outlet will depend on the environment in which the silencer plate is being used. Generally, the inlet should be located such that it is not too close to any walls or other objects that could interfere with the free flow of...
So I can't be sure what the professor is asking us to prove.For the Vertex Cover addition, I would have to think about the application scenario for a bit.
For case I, the induced voltage is positive. This means that when a current flows into the pole face, the induced voltage will be positive. For case II, the induced voltage is zero. This means that when a current flows beyond the pole edges, the induced voltage will be zero.
I'm guessing the pressure is higher at the constriction and afterwards because of the compression of the air molecules at the area of constriction, but I don't get the fact that the pressure increases with increasing volumetric flow.
A:I'm not sure what you mean by 'a point source' but the equation you gave for the flux is correct.To derive it, start with the diffusion equation$$\nabla^2 \phi = - \frac{S}{D}$$where $\phi$ is the neutron flux and $S$ is the source term. Then, assume spherical symmetry so that the diffusion...
The percentage of elastic deformation would be 100% - 15% = 85%. The plastic deformation would be 15%.The length of the wire before it ruptures under its own weight can be calculated by using the following equation:Length = (Force)/(Area*Yield Stress)Force = (Density)*(Volume)*(Gravity)Volume =...
