Consider two signals, (t) and y(t), each with a fundamental period of T = 2 seconds. The Fourier series coefficients of each of these signal are ak, x = (10.250j 0 - 0.257j)
ba, x = (-0.50j 0 1 100,5j)
What is the result of multiplying the two signals in the time domain?

What precautions should you take to prevent injuries when dealing with heavy loads?

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
