Question beam abc is supported by a three-bar truss at, Ask an Expert

Engineering

Question: Beam ABC is supported by a three-bar truss at point C and at A by an elastomeric pad that is equivalent to a roller.

(a) Compute the vertical deflection of point B in Figure due to the applied load.

(b) Compute the change in length of member DE required to displace point B upward 0.75 in. Is this a shortening or lengthening of the bar? Given: E = 29,000 kips/in.2, area of all truss bars = 1 in.2, area of beam = 16 in.2, I of beam = 1200 in.4.
