Problem 14.76

A uniform beam is suspended horizontally by two identical vertical springs that are attached between the ceiling and each end of the beam. The beam has mass 225 kg, and a 175-kg sack of gravel sits on the middle of it. The beam is oscillating in SHM with an amplitude of 40.0 cm and a frequency of 0.600 cycle>s. (a) The sack falls off the beam when the beam has its maximum upward displacement. What are the frequency and amplitude of the subsequent SHM of the beam? (b) If the sack instead falls off when the beam has its maximum speed, repeat part (a).

PHYS 1961 SEC 001 September 25, 2016 Group Members: Lab Report #2 Introduction: The purpose of this lab was to introduce us to the two­dimensional kinematic equations, explore the dependence or independence of the x and y motion of a projectile, practice experimental procedures, predict the path of the projectile, and graph the data which our experiment procures. Using Newton’s Second Law of Motion, we know that if gravity is the only force acting upon the projectile, then the acceleration is constant and the following equations apply: 1) x=v t0x 1 2 2) y=y +0 t−0 y 2 v
