The truss is supported by a pin connection at \( A \) and a roller at \( L \). It is loaded as shown. Use the picture below to determine the forces in members \( \mathrm{HJ}, \mathrm{IJ} \), IK. Report all answers in \( \mathrm{kN} \) but do not enter units in Canvas. Report positive values for members in tension and negative values for members in compression.
