Mechanics Homework 12-1 322 - Equilibrium of Force System Name_______________ Mr. Haynes Date_______________

Problem 12-1 The Fink truss shown in Fig. P-322 is supported by a roller at A and a hinge at B. The given loads are normal to the inclined member. Determine the reactions at A and B. Hint: Replace the loads by their resultant.

$$R_A = 4618.80 \, \text{ lb}$$

$$R_B = 4618.80 \, \text{ lb } 30^\circ \text{ CW from negative } x \text{ axis.}$$
