Question-4 Find the magnitude and nature of the forces in members AC, AD, DB, CE, CF and FD by section method. A B 1 kN 2 m 2 kN C 2 m F 2 m 2 m 2 m

For the truss shown, Find the height of the truss?Analyze the load on each member of the truss?

Determine the force in members GD of the truss in kN and state if the members are in tension or compression. B 1300 N 1.2 m 13 12 0.9 m 0.9 m F -1.2 m 1.2 m-1.2 m-1.2 m- Note: answer as negative value if the force is in compression and positive if it is in O -1 O 1 O 2 O -2 O -2.5 O 2.5 O 1.7 O -1.7

5)Determine the forces in all members of the truss. There is a pin at A and a roller at D. In answers for truss forces remember you must always indicate if a member is in tension (T) or compression (C); for example, if there was a member JK carrying a 2 kip compressive load the answer would be FJ = 10 K (C) 3 m G 10 kN 6kN E -2.5 m- -1.5 m-1.5 m- -2.5 m

Using the method of joints, determine the force in all truss bars. Indicate tension or compression.

*For the Howe bridge truss shown, d=11 ft,F1=3150 lb, F2=2150 lb, F3=2550 lb, and F4=4150 lb.* Pt A. Determine the forces in members CD, DH, and GH. Pt B. Determine the forces in members HI, BH, and BC.

The steel truss (E =200 GPa) shown in figure below has a cross-sectional area of 1920 mm². Determine: a. The largest allowable load F if the change in length of member BD is not to exceed 1.6 mm and a factor of safety of 2.5. b. The displacement of support D due to the load calculated in part a. 5m 6m A C F

TEXT:A planar construction is composed of two beam elements and two axial rods. These arejoined with frictionless joints, as indicated on the sketch. The structure is applied an outer concentrated load P=8kN in node G and a downwardevenly distributed load q=4kN/m between junctions A and D. The beam ABCD and EFG are torque rigid,while the axial rods BF and CF only absorb forces in the direction of the rods. A) Calculate the rod forces and for the external given load effect.B) Calculate the bearing reactions for the external given load effect.

A Howe scissors roof truss is shown. A Howe scissors roof truss is loaded as shown. Determine the force in members Gl, Hl, and HJ when P1 = 1 kips and P2 = 2 kips. Note: please double check your answers!. Thanks
