Consider a straight screw dislocation parallel to a rigid surface, constrained not to deform. Show that the screw is repelled from the surface by a force equivalent to an image dislocation of the same sign and magnitude. (This example is relevant to the situation of a dislocation near a surface with a hard oxide layer upon it.)

Consider a particle which is constrained to move along the surface of the sphere of radius 5, centered at the origin. (a) If we write r(t) for the motion, write down the condition ‘constrained to move along the surface of the sphere of radius 5 centered at the origin’ in terms of r(t). (Hint. For later use, try to get rid of square roots.) (b) Explain why, for such a motion, we must have r 0 (t) ⊥ r(t). (Hint....

A toy airplane is flying in a straight horizontal (parallel to the ground) path with a speed of vi = 34.0 m/s. Suddenly, the airplane's engines stop (at t=0). Using an x-axis that is horizontal and along the plane's original velocity and a y-axis that is vertical with positive away from the ground, the airplane now has an acceleration given by the following expressions: ax(t) = − t2/C ay(t) = − g [ 1 − vx(t)/vi ] where C =...

An iron plate 0.2m thick is magnetized to saturation in a direction parallel to the surface of the plate . A 10 GeV muon moving perpendicular to that surface enters the plate and passes through it with relatively little loss of energy. Calculate approximately the angular deflection of themuon’strajectory, given that the rest-massenergy of the muon is 200 MeV and that the saturation magnetization in iron is equivalent to 1.5·10^29 electron moment spercubicmeter.

A sled with mass 100 kg moves in a straight line on a horizontal surface as it is being pulled by a force 250 N at an angle of 35° with the direction of motion. A force of friction of 30 N acts on the sled. At one point in its path, its speed is 3.0 m/s; after it has traveled a distance d beyond this point, its speed is 8.0 m/s. Use the work-energy theorem to find the total...
