The pin-connected truss shown below is loaded by a 30 kN horizontal force at H and a  15 kN vertical force at J. A) Find the support reactions at A and T. B) Identify all zero-force members by writing a zero over the corresponding member(s)  on the figure below. C) Determine the axial force in member HK using the  method of sections .  Express  your answer in terms of magnitude and either tension or compression. D) Determine the axial force in member KL using the  method of joints .  Express your  answer in terms of magnitude and either tension or compression.
