Problem 1. Use virtual work method and determine the following unknowns on the frame shown below. Use \( \mathrm{I}=800 \times 10^{6} \mathrm{~mm}^{4} \) and \( \mathrm{E}=200 \mathrm{GPa} \). Show complete and organized solution. Round-off your answers to two decimal places. a. Vertical deflection at point \( \mathrm{C} \) in \( \mathrm{mm} \). b. Horizontal displacement of joint \( \mathrm{B} \) in \( \mathrm{mm} \). c. Slope of at \( D \) in degrees.
