A support beam, within an industrial building, is subjected to vibrations along its length; emanating from two machines situated at opposite ends of the beam. The displacement caused by the vibrations can be modelled by the following equations,

?1 = 3.75 sin (100?? +2π/9)

?2 = 4.42 sin (100?? −2π/5)

a) when both machines are switched on how many seconds does it take for each machine to produce its maximum displacement?

b) at what time does each vibration first reach a displacement of -2mm?

A finite rod of length LLL has total charge qqq, distributed uniformly along its length. The rod lies on the x -axis and is centered at the origin. Thus one endpoint is located at (−L/2,0)(−L/2,0), and the other is located at (L/2,0)(L/2,0). Define the electric potential to be zero at an infinite distance away from the rod. Throughout this problem, you may use the constant kkk in place of the expression 14πϵ014πϵ0. Part A What is VAVAV_A, the electric potential...
