Given the following truss, determine: a. The external reactions of the truss (Ray, Rcx, Rcy). b. The internal forces in all elements (tension or compression), applying the method of nodes.c. Draw the proposed truss, identifying which elements are in tension and which are in compression.

Determine the force in member BE of the loaded truss. The force is positive if in tension, negative if in compression. 6 kN 2 m C 6 kN E 2 m B 7 kN 2 m A 4 m

Determine the forces in members AB, BI, and CI of the simple truss. Note that all curved members are two-force members. The forces are positive if in tension, negative if in compression. Arc of radius 44.0 m H B C D YL E YL 14 m 14 m 19 m 14 m 14 m 21 m F

The members of the truss are assumed to be pinconnected. If member CB is an A-36 steel rod of 40 mmdiameter, determine the maximum load P that can besupported by the truss without causing the member tobuckle. For A36 steel E=200 GPa and σY = 250 Mpa

For the given truss a. Draw the free-body diagram without the zero-force members. b. Use the method of sections to find the forces in members RS, MG, and ER. Assume that member ER carries twice the magnitude of the force carried by the member DE. c. Use the method of joints to find the forces in members VW and OW. Indicate whether the forces are in tension or in compression. 5 kN 2 kN B D 50° G E 0.5 m 0.5 m R T 0.25 m 30° 3 KN X. 0.5 m 4 kN 0.6 m 1.2 m 1.2 m 1.2 m 1.2 m 1.2 m
