The following is used to model a wave that impacts a concrete wall created by the US Navy speed boat.1. Derive the complete piecewise function of F(t) and F()The concrete wall is 2.8 m long with a cross-section area of 0.05 m2. The force at time equal zero is 200 N. It is also known that the mass is modeled as lumped at the end of 1200 kg and Young’s modulus of 3.6 GPa2. Use *Matlab to simulate and plot the total response of the system at zero initial conditions and t0 = 0.5 s
An aluminum wire having a cross-sectional area equal to 4.60 x 10-6 m? carries a current of 7.50 A. The density of aluminum is 2.70 g/cm³.
Assume each aluminum atom supplies one conduction electron per atom. Find the drift speed of the electrons in the wire.
1.95E-4
The equation for the drift velocity includes the number of charge carriers per volume, which in this case is equal to the number of atoms per
volume. How do you calculate that if you know the density and the atomic weight of aluminum? mm/s
Show that F(x, y, z) = xy + xz + yz has the value 1 if and only if at least two of the variables x, y, and z have
