SOLVE THE GIVEN TRUSS. DETERMINE BAR MEMBER FORCES AND STATE IF IT IS COMPRESSION OR TENSION

The cross-sectional area of each members of the truss is 1.8 in². Calculate the stresses in members CE and DF. Indicate tension or compression.

Determine the force in BE of the truss shown. indicate whether the members are in tension or compression.

1.5 m L E 2 t t T t A -2 m 3 kN D B 2 m Determine the force in each of the truss members using method of joints. Draw all pertinent free-body diagrams and indicate tension or compression for the internal forces. Identify any zero-force members.< C I=

B 6 ft D 8 ft 8 ft 8 ft 33 kips C The cross-sectional area of each member of the truss is 1.75 sq. in. Calculate the stresses in ksi in members DF and EF. Indicate tension or compression. 6 ft E

I tried to solve the first problem by cutting a section at s and then taking the sum of moments with respect to point H (HJ, HI, DJ are now not relevant) which looks like it yields compression which seems right but I keep on getting the wrong answer

truss. need asap

Determine the force in each member of the loaded truss. Make use of symmetry of the truss and of the loading. Forces are positive if in tension, negative if in compression.

For the truss shown in Figure 2.3b, determine the force in member KP if x = 5 m, y = 7 m and P = 7.94 kN. Indicate whether the member is in tension or compression. (Note: Use negative sign (-) if the member is in compression.) 7 panels at x m = 7x m В J D K L y F A х М N H G P P kN P kN

Problem 2: Determine the force in ALL the members of the truss. State if the members are in tension or compression. Show all your work to receive full credit. (Hint: It is not needed to find the reaction forces at C and E if you use the Method of Joints). Note: P1= 1000 lb and P: = 500 lb B C30 45 999 4 ft E 550 D. -4 ft- - 4 ft- 999 299
