The question as text
A uniform beam is clamped at one end. A metal block of mass m is fixed to the other end of the beam causing it to bend, as shown in Fig. 3.1. x clamp beam equilibrium position displaced position metal block mass m Fig. 3.1 The block is given a small vertical displacement and then released so that it oscillates with simple harmonic motion. The acceleration a of the block is given by the expression a x m k =- where k is a constant for the beam and x is the vertical displacement of the block from its equilibrium position.
