Speed of waves, v, on a string depends on its mass m, length l, and tension Q? Using dimension analysis derive an expression of how V, relates with m, l and Q.
Dimensions of all the terms:
Speed, v : LT -1
Mass, m : M
Length, l : L
Tension, Q : A force = mass x acceleration: MLT -2

In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall. the cylinder begins to rotate about a vertical axis. then the floor on which the passengers are standing suddenly drops away! if all goes well, the passengers will “stick” to the wall and not slide. clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. part a what is the minimum rotational frequency, in rpm, for which the ride is safe? express your answer using two significant figures. f f = rpm
