Group 3 Unit 5 3. Imagine a stiff ruler that's lying at the edge of a table so that one end of it is on the table and the other end is free in the air. If you hold the ruler's supported end against the table with one hand and pluck its free end with the other hand, the ruler will vibrate up and down. a. Why does the ruler's frequency of oscillation decrease when you extend more of it off the table? If you extend more of the ruler off the table then you are extending the springy portion of the ruler in return increasing the mass and making the ruler less stiff. Stiffness is measured by how sharply the restoring force strengthens as the oscillator is displaced from equilibrium. b. Why doesn't the ruler's frequency of oscillation depend on how hard you pluck it? It’s a harmonic oscillator, which means its frequency of oscillation doesn’t depend on amplitude. The ruler undergoes a predictable amount of oscillation and does not change. c.
