Part 1: A support beam, within an industrial building, is subjected to vibrations along its length; emanating from two machines situated at opposite ends of the bear. The displacement caused by the vibrations can be modelled by the following equations, x₁ = 4.2 sin(100nt +0.59) mm x₂ = 6.1 sin(100mt-0.42) mm Your senior engineer asked you the followings: (a) State the amplitude, periodic time, frequency and phase angle (in degrees) for each of these waves.
