$[$Question ID $461705)$ Three foroes are applied to a truss that is roller$-$supported at A allu supported at $H$ Joints I,$J$ and $K$ lie on a straight line.

The force applied at $D$ points upwards and the forces at $E$ and $G$ point downwards.

Note the figure is not neoessanily to scale

Calculate the magnitude of the vertical component of the support reaction at H on the truss and stipulate its direction. Also calculate the length of EJ and the angle between members DE and D J

Cal cul ate the forces that develop in members DE$,$ DJ and II and indicate whether they are in Tension or compression.

calculate the forces that develop in members EG and EJ and indicate whether compression or Tension.
