Beam ABC is supported by a three-bar truss at point C and at Aby an elastomeric pad that is equivalent to a roller.(a)Compute the vertical deflection of point B in Figure P10.39 due to the applied load. (a) Compute the change in length of member DE required to displace point B upward 0.75 in. Is this ashortening or lengthening of the bar? Given: E = 29,000 kips/in 2, area of all truss bars = 1in2, area of beam = 16 in,I of beam = 1200 in4.
