A string with both ends held fixed is vibrating in its third harmonic. The waves have a speed of 195 m/s and a frequency of 240 Hz. The amplitude of the standing wave at an antinode is 0.350 cm. I have already correctly calculated the amplitude of the string at a point 24 cm from the left of...

Water flows steadily from an open tank. The elevation of point 1 is 10.0 m, and the elevation of points 2 and 3 is 2.00 m. The cross-sectional area at point 2 is .048 m^2; at point 3 it is .016 m^2. The area of the tank is very large compared with the cross-sectional area of the pipe. I...

r is the radius of the circle created as the masses on the rods swing in a circle. theta is the angle between the rod and its vertical support (perpendicular to the ground) as the masses swing outward EDIT: What you said got me to thinking and I got the answer now. Thanks

An amusement park ride consists of airplane-shaped cars attached to steel rods. Each rod has a length of 14.2 m and a cross-sectional area of 7.80 cm^2. Each car plus two people seated in it has a total weight of 1950 N. When operating, the ride has a maximum angular speed of 7.50 rev/min...
