Question: Tachometers are a reed-type frequency-measuring instrument consisting of small cantilever beams with weights attached at the ends. When the frequency of vibration corresponds to the natural frequency of one of the reeds, it will vibrate, thereby indicating the frequency. How large a weight must be placed on the end of a reed made of spring steel 0.1016 cm thick, 0.635 cm wide, and 8.890 cm long for a natural frequency of 20 cps?
A 300-m-wide river flows due east at a uniform speed of 4.4 m/s. A boat with a speed of 7.6 m/s relative to the water leaves the south bank pointed in a direction 25o west of north. How long does it take for the boat to cross the river
Sketch a reasonable blade section. Do you think that the actual blade exit angle will need to be less or greater than 15°? Why?
Protons carry an electric charge ofe = 1.60×10−19 C, electronscarry a charge of −e, and neutrons are electricallyneutral. Protons and neutrons have a mass of1.67×10−27 kg, and electrons have a mass of9.11×10−31 kg.
