2- For the truss shown below, the internal force in member BC is equal to: (a) 3 kN (b) 6 kN (c) 0 kN (d) 15 kN (e) none of the above

3- For the cantliever beam shown below, the moment at the fixed end A is equal to: (a) 36 kN.m (b) 108 kN.m (c) 72 kN.m (d) 33 kN.m (e) none of the above

5- Using this FBD, you find that FBC = – 500 N. Member BC must be in A) Tension B) Compression C) Cannot be determined

Question 2 Determine the magnitude and orientation, measured counterclockwise from the positive y axis, of the resultant force acting on the bracket.

Question 3 For the truss shown in Fig. Q4, determine the force in each member of the truss using joint method of analysis. Indicate whether the members are in tension or in compression. 1 m

Question 4 The force F acts on the end of the pipe at B. Determine a) the moment of this force about point A. F= 70N a= 0.9 m b= 0.3 m c= 0.7 m Θ= 60 deg.
