Question

Consider the truss shown in the figure, built from three struts attached by three pins. The truss supports a downward force of 

F = 1,250 N

 applied at the point B. Assume the mass of the truss is negligible, the pins are frictionless, and the supports at A and C are also frictionless.

 

 

(a)
Assuming ?1 = 25.0° and ?2 = 49.0°, what are nA and nC? (Enter the magnitudes in N.)
nA= NnC= N
(b)
The force any strut applies on a pin must be directed along the length of the strut as a force of tension or compression. What are the directions of the forces that the struts exert on the pins joining them?
strut AB on joint A:   strut AB on joint B:   strut BC on joint B:   strut BC on joint C:   strut AC on joint A:   strut AC on joint C:   
Find the force of tension or of compression (in N) in each of the three struts.
