All the tension/compression members of the frame structure shown in the figure are pin-jointed and of equal length and negligible weight. An external load \( P=28.1 \mathrm{kN} \) is applied vertically at joint \( \mathrm{E} \). The frame is pin-connected at fixed support A and supported by a roller at \( \mathrm{D} \). What is the force in member \( A B \) ? Input your answer as a value only in \( \mathrm{kN} \) to one decimal place without \( +/- \) sign. All the tension/compression members of the frame structure shown in the figure are pin-jointed and of equal length and negligible weight. An external load \( \mathrm{P}=25.4 \mathrm{kN} \) is applied vertically at joint \( \mathrm{E} \). The frame is pin-connected at fixed support \( A \) and supported by a roller at \( D \). What is the force in member AE? Input your answer as a value only in \( \mathrm{kN} \) to one decimal place without \( +/- \) sign. All the tension/compression members of the frame structure shown in the figure are pin-jointed and of equal length and negligible weight. An external load \( P=16.7 \mathrm{kN} \) is applied vertically at joint \( \mathrm{E} \). The frame is pin-connected at fixed support A and supported by a roller at \( D \). What is the force in member BE? Input your answer as a value only in \( \mathrm{kN} \) to one decimal place without \( +/- \) sign.
