摘要：This paper presents a new laboratory experiment recently conducted at Dalhousie University where Apple iPod Touches and iPhones were used to provide Hands On Programs (HOPs). Both iPod Touches and iPhones contain accurate 3-axis accelerometers that can be used to take real measurement of vibrating systems. The Apple App Store contains a number of applications that utilize the built-in accelerometers. A basic free App was downloaded by the students. The department rapid prototyped a simple iPod / iPhone holder attached to a cantilevered vibrating beam and after a brief familiarization period the students collected the raw data and emailed themselves the results over the classroom Wi-Fi. The students then analyzed the data using an instructor-supplied spreadsheet. This lab allowed the students to be introduced to such concepts as: data collection, vibration of continuous systems, resonant frequencies, quality factor and damping, and finally data analysis.
