Homework Statement
The total length of the composite body is 4.5 feet. Before the propellant is burned, the projectile weighs 23 lbf. After the propellant burns, the remaining projectile weighs 16 lbf. Before the propellant is burned, the mass center is located 2.6 feet from the projectile...
Hi,
I am in a numerical methods for PDE's class and have just been introduced to the ADI method. My teacher has given a general 2D heat equation to numerically compute using ADI with Crank-Nicolson and ADI with Peaceman-Rachford schemes. I understand what ADI is doing, I just don't know...
I am really confused with the concept of Neumann Boundary conditions. For the simple PDE
ut=uxx for the domain from 0<=x<=1
I'm trying to use a ghost point (maintain a second order scheme) for the Neumann Boundary condition ux(0,t) = 0.
I understand that I can setup a scheme to...

The Attempt at a Solution
I know I only have tension, weight, and a normal force acting on my particle but I...
Homework Statement
Please see attachment.
When θ = 0, mass m is at the bottom of the inclined plane.
If I create a frame at origin O, with axes along the bottom of the plane and the dotted line (as shown in the picture), will my magnitude of the vector from O to A (along the dotted...
Homework Statement
A collar of mass m slides without friction along a circular track of radius R as
shown in THE ATTACHMENT. Attached to the collar is a linear spring with spring constant K and
unstretched length zero. The spring is attached at the fixed point A located a distance
2R from...
