Question 4 The figure below shows three physical pendulums consisting of identical uniform spheres of the same mass that are rigidly connected by identical rods of negligible mass. Each pendulum is vertical and can pivot about suspension point O. Rank the pendulums according to period of oscillation, greatest first. (Use only the symbols > or =, for example b=c>a.) (a) (b) (C)

A simple pendulum is 0.44 m long. At t = 0 it is released from rest starting at an angle of 18°. Part A Ignoring friction, what will be the angular position of the pendulum at t = 0.35 s?

Express your answer in degrees. ηVM ΑΣφ 03.45 = Submit Request Answer Part C Ignoring friction, what will be the angular position of the pendulum at t = 6.00 s?

Chapter 15, Problem 051 GO In the figure, a stick of length L = 1.9 m oscillates as a physical pendulum. (a) What value of distance x between the stick's center of mass and its pivot point o gives the least period? (b) What is that least period?

Question 6 Shown here is a rod of length = 1.17 m and mass m = 583 g that is pivoted at one end. Centered on the other end of the rod is a solid disk of radius R = 34.1 cm and the same mass as the rod. If this was turned into a physical pendulum with the given pivot, what would be the period of the pendulum?
