The truss ABC is constructed of three titanium (E Ti ​ =17.4×10 3 ksi) members. A horizontal force of 1.8 kip and an unknown force P are applied to the truss at point B as shown. Member AB has a cross-sectional area of 0.1in 2 , member BC has a cross-sectional area of 0.0025ft 2 , and member AC has a cross-sectional area of 0.2 in2.   b) Determine the magnitude of the force P that is required to displace the roller at point C to the right by .03 inches.

For the determinate 2D truss shown:(a)  Compute the reactions and the internal forces of all the truss elements using the methodof joints.(b)  Compute the reactions and the internal forces of all the truss elements using the method
