Problem Set 2

1. Use the method of sections to find the force in member AK and EQ. Load P is equalto 400 lb and the angle is 45. Note that the truss is supported by a pin support at A

and a rocker at V.

(Answer: EQ = 240 lb T, AK = 400 lb C)

2. For the truss shown:a. Use the method of sections to find the force in members BF and FI. The internal force in

member BC is 725 N, Tension.

b. Use the method of joints to find the force in members OS and NR.

(Answer: FI = 1307.01N C, BF = 0, OS = 409.58N C, NR = 409.58N C)
