Question:
Determine the Fourier series for the full wave rectified sine wave:
Answer:
Sketch the Function and work out the period (L):
The graph has a period of L=4𝜋.
The function is symmetrical in the y-axis. Therefore it is an even function and will contain no sine functions.
It has a period 4𝜋 so we can use the formula for Fourier Series of periodic functions for any period with L = 4𝜋.
Question: The direct stresses acting on an element of material, on orthogonal planes, are 85N/mm^2 (tensile) and 45N/mm^2 (tensile) together with a shear stress of 15N/mm^2. What is the factor of safe
Question: A thin cylinder of 3m diameter is subjected to an internal pressure of 2.5MN/m^2. Using a factor of safety of 2.2 and a yield stress of 300MN/m^2, calculate the wall thickness based on the a
Question: A hole in a pressure vessel end plate repair casting is being drilled using a radial arm drill. The distance from the drill point to the centre of the drill column is 1.2m. The drill column
