F1 2m F2 A 3.2m 1.8m AF, = 153 N load and a F, = 99 N are applied to the frame which is supported by pins at A and B. These loads are applied perpendicular to the beams. The two beams AC and BC make a right triangle. You may neglect the weight of the members. Find the magnitude of the force at pin C. For this problem, use the coordinate frame given. 1.5 m 4------ 1.5 m +----- 2.4m

The pyramidal truss section BCDEF is symmetric about the vertical x-z plane as shown. Cables AE, AF, and AB support a 3.3-kN load. Determine the force in member BE. The force is positive if in tension, negative if in compression. 220 mm 220 mm 270 mm 270 mm 350 mm E Answer: BE = i 290 mm A 290 mm 3.3 KN B KN

Determine the magnitude of the pin force at A.Assume W = 665 lb, a = 3.7 ft, b = 2.9 ft, r = 8 in.

The ABD bracket is supported by a pin at A and the cable DE. Determine the internal forces immediately to the left of the load.Template: (On CD) F= 270 N; M=43.2 N.m; V = 90 N

Determine the force in each member of the loaded truss. All triangles are 3-4-5. Enter a positive number if the member is in tension, negative if in compression.

Determine the force in each number pf the truss, and state of the members are in tension or compression, set θ=30°

Determine the force in each member of the loaded truss. The force is positive if in tension, negative if in compression.

Determine the forces in members BC and CF of the loaded truss. Enter a positive number if in tension, negative if in compression.
