Answer #1

Question:

We have to determine the suppprt reactions of he given truss;

We determine the suppprt reactions by considering the equilibrium of the truss as a whole.

~3 KN Question Determine reaction forces : 0=30 given) comportent of force c m na 1, Al the direction W, A Sign Convention T

By using the sign conventions as shown above we get:

$\boldsymbol{A_{x}=1.1957 \approx 1.2\; \; kN}$ (towards left)

$\boldsymbol{A_{y}=0.875\: \: kN}$ (upwards)

$\boldsymbol{C=3.6084 \approx 3.6 \: \: kN}$ (perpendicular to the surface of roller towards left and upwards)

(all directions are shown in the figure)
