Question 3 a) A mass of 10500grams is attached to a beam at B. The beam is of negligible mass and is pivoted at 0 in order to undergo simple harmonic motion (SHM). The spring attached at A has a spring constant of 7250N/m. If the mass at B is displaced by a small angle determine the frequency of the system. A 125m 375m 1. Find the periodic time of oscillation. when the mass is at a point 5mm from the equilibrium position, B b) State the two conditions necessary for motion to be considered simple harmonic motion (SHM). c) A mass of 43kg is suspended from a spring which has a stiffness of 26000N/m and it vibrates with an amplitude of 19mm.
