Problem 07.015.a -Determine the stress components after clockwise rotation of the element for the given state of stress. Determine the normal and the shearing stresses after the element shown has been rotated through 25 clockwise. (Round the final answers to two decimal places.) Normal stresses: _x= _____ksi (+ tensile; - compressive) _y=_____ k si (+ tensile: -compressive) Shearing stress: Tx'y'= ____ k si+ CCW on positive x-face)

After plotting the voltage waveform, obtain a 0.2-mp expressions and generate plots for (t), p (t), and w (t) for i by capacitor. The voltage waveforms are given:(a) v_1(t) = 5r(t) - 5r(t 2) V (b) v_2(t) = 10u(-t) + 10u(t) - 5r(t-2) + 5r(t-4) V (c) v_3(t) = 15u(-t) + 15e^(-0.5t) u(t) V (d) v_4(t) = 150[1 - e^(-0.5t)] u(t) V
