Asteel pipe having a length of 1m, and outside diameter of .2m, and a wall thickness of 10mm, is subjected to an axial compression of 200kn. assuming the modulus of elasticity of 200 gpa and a poisson's ratio of .3, find the following. a) the shortening of the pipe b) the increase in the outside diameter c) the increase in wall thickness

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 3.00 ms . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
