2018 F = ma Exam A — Question 14

Three identical masses are connected with identical rigid rods and pivoted at point A. If the lowest mass receives a small horizontal push to the left, it oscillates with period T . If it instead receives a small push 1 into the page, it oscillates with period T . The ratio T /T is 2 1 2 A
