An ultrasonic transducer, of the type used in medical ultrasound imaging, is a very thin disk (m = 0.14 g) driven back and forth in SHM at 1.1 MHz by an electromagnetic coil. (a) The maximum restoring force that can be applied to the disk without breaking it is 40,000 N. What is the maximum oscillation amplitude that won't rupture the disk? (b) What is the disk's maximum speed at this amplitude?
Two parallel rods are each 0.50 m in length. They are attached at their centers to either end of the spring (spring constant = 150 N/m) that is initially neither stretched nor compressed.
