The structure in Figure P16.1 is composed of three pin-connected bars. The bar areas are shown in the figure. Given:E = 30,000 kips/in2.
(a) Compute the stiffness coefficientK associated with a 1-in vertical displacement of joint A.(b)Determine the vertical displacement atAproduced by a vertical loadof 24 kips directed downward,(c)Determine the axial forces in all bars.
