A simple truss is shown in the figure below. The truss is loaded with horizontal and vertical force 15 kN and 25 kN r espectively. The force in member AB will be ____ kN.
-
- 10
- 20
- 30
- 15
Correct Option: B
Methods of Joints through analysis of pin-jointed plane trusses helps in the calculation of each member forces. Support at A is a roller, therefore it has only vertical reaction and no horizontal reaction.
