3. A precision instrument modelled as a block of mass m = 2kg and a spring k = 98 N/m rests on a table that is subject to a harmonic acceleration (t) = 0.1 sin 6 t (m/s2), as shown in figure QB1.3. AX AY k m (t) A Figure QB1.3 a) determine the steady-state amplitude of the relative displacements of the block of mass m (X). Marks 5 b) Determine the amplitude of the steady-state vibration of the absolute displacement of the block of mass m (X = X + Y). 3.
