Question: Waves on a Stick a flexible stick 2.0 m long is not fixed in any way and is free to vibrate. Make clear drawings of this stick vibrating in its first three harmonics, and then use your drawings to find the wavelengths of each of these harmonics. (Hint: Should the ends be nodes or antinodes?)
A heavy piece of hanging sculpture is suspended by a 90 cm-long, 5.0g steel wire. What is the mass of the sculpture
A person exerts a horizontal force of F = 179N in the test apparatus shown in the drawing. (h = 0.33 m.) Determine the horizontal force M that his flexor muscle exerts on his forearm.
What minimum coefficient of static friction is required? Is the reply you found reasonable? In other words, is he probable to stay on the merry-go-round.
