Determine the pressure in each member that the loaded truss. Make use of the the opposite of the truss and also of the loading.

Calculate angle induced by truss members to uncover forces induced in members.
Calculate angle of the truss at allude A by using the formula:
Here, 4 m is the elevation of the truss and also 5 m is the width of truss in ~ inclined member in truss.
Calculate force acting at suggest E by taking moments around point A:
Here, 30 kN force at point H, is exhilaration at a distance of 5 m from point A, 60 kN pressure at suggest G, is acting at a distance of 10 m from suggest A, 30 kN pressure at point F, is acting at a distance of 15 m from point A and
Write equation that equilibrium because that the horizontal pressures acting ~ above the truss:

Write equation the equilibrium because that the vertical pressures acting ~ above the truss:
Here, 30 kN is the force acting at point H, 60 kN is the force acting at suggest G, 30 kN is the pressure acting at suggest F and also 60 kN is the reaction force acting at point E.
