Assume there are two screw dislocations in a FCC crystal. If the two dislocations are parallel to each other and both have Burgers vector of [101], what will be the force on a unit length of one dislocation that is a. 2 exerted by the other dislocation if the two dislocation are 100 nm apart from each other? Assume a 0.25 nm, the shear modulus is 3 GPa.

The figure below shows two parallel wires (#1 and #2) separated by a distance d and carrying currents 1 and 21 respectively in opposite directions. It also shows three points (P1, P2, and P3) where we wish to determine the magnetic field (magnitude and direction). Let's define a unit of magnetic field as fol, and use standard sign convention, namely into the page is negative and out of the page is 2nd positive. Determine the magnetic field at the following...

The figure below shows a top view of a bar that can slide on two frictionless rails. The resistor is R = 5.00 Ω, and a 2.50-T magnetic field is directed perpendicularly downward, into the page. Let ℓ = 1.20 m. A vertical bar and two parallel horizontal rails lie in the plane of the page, in a region of uniform magnetic field, vector Bin, pointing into the page. The parallel rails run from left to right, with one a...
