Question 4 A Beam Of Negligible Mass And Thickness Is Supported By A Roller At A And A Pin At B Three Load Forces Of 2 1 (40.33 KiB) Viewed 35 times

Question 4 A beam of negligible mass and thickness is supported by a roller at A and a pin at B. Three load forces of 2.5 kN, 1.5 kN and 6 kN are applied as shown in the diagram. 6 KN 1.5 KN 2.5 kN T-2m- +2m1 -2 m- 4 m 2 m- The system is in equilibrium. a. Draw the free body diagram for the beam showing all the external load forces acting on the beam and including the reaction forces at roller A and at pin B. b. Use the conditions for equilibrium to determine the horizontal and vertical components of the reaction support forces at roller A and at pin B. [4] Σ Fx = 0 Σ Fy = 0 Σ Mpoint = 0 B
