Determine how far it bottom end is displaced due to gravity in micrometers when it is suspended from a celing in the vertical position from its top end. 9.81 m/s2, de 7 cm. L-195 cm) Yanitiniz:

Answer 1

solution iven. ceiling f = 7800 kg/m3, g = 9.81 m/s² E = 200Gpa L=195cm I d= 7cm A = I (7)² = 38.48 cm² or 3848 mm? Kleight of member (w)= Volume x density

w = (AxL) xf = (10:07)+x1.95) * 7300 -.. - 58.53 kg -- ( napr kg ] = 58.53 x9.81 w =574.2N - This is force - acting due to self weight kle know the due to self weight AL = WL 2AE 574.2 x 1.95x103 2x 3848 x 200x103 AL=0.727 810 mm or TAL=0.727 micron
