E-B beam has L=2M, A=1 cm^2 and E=100 MPA, H=1 cm and its deflection is v(x) = -0.001x(M) at x=1M What is the angle of rotation of its cross section What is the stress at x=1M for y=-H/2, 0, +H/2 What is the stress at the end x=2M for y=-H/2, 0, +H/2 Note: Write the formula first and then calculate.
