A human wave. During sporting events within large, densely packed stadiums, spectators will send a wave (or pulse) around the stadium (the figure). As the wave reaches a group of spectators, they stand with a cheer and then sit. At any instant, the width w of the wave is the distance from the leading edge (people are just about to...

The electric field of a point charge decreases as 1/r2, with r being the distance from the charge. The magnetic field of a magnet decreases as 1/r3 far away from the magnet. Why is the dependence on the distance r different in these two cases?

EXAMPLE 4.29 The slender bar, pinned smoothly at O, is released from rest in the position showr in Figure E4.29a. After a rotation of 45°, its angular speed is (3g)/(2/). Find at that instant the axial force, shear force, and bending moment in the bar at point A, which is one-fourth the length of the bar from its free end....
