Unformatted text preview: center of mass is 14 cm from the hole at the end. 2. You hang the wrench from a spring that has a constant of 360 N/m and the spring stretches 3.2 cm. 3. You hang the wrench from hook, displace the wrench 11 from the vertical, release the wrench, and determine the period of motion is 0.90 sec. Determine the mass moment of inertia about the hook, and about the center of mass. EF 152 Spring, 2009 Lecture 3-5 5 SHM The design of a timing mechanism requires that a mass of 3.2 grams undergo 6 oscillations per second when it is attached to a spring.
