Question

Problem 1. Find the tension in the cable and the reaction forces at the pin. Each beam in the truss is 1 m long and weighs 1000 N. Neglect the joints between beams. The cable is at an angle of 30° from the +x axis and the truss is at an angle of 150° from the +x axis. Problem 2. A truss is subjected to three loads. The truss is supported by a roller at A and by a pin joint at B. What is most nearly the reaction force at A? 2000 kN 3000 kN 4000 kN 10 m 7 m 7 m 7 m (A) 3800 kN (B) 4400 kN (C) 4900 kN (D) 5000 kN
