The thickness of a rectangular steel girder equals h. Using the equation of Problem 1.301, find the deflection X caused by the weight of the girder in two cases: (a) one end of the girder is embedded into a wall with the length of the protruding section being equal to 1 (Fig. 1.78a); (b) the girder of length 21 rests freely on two supports (Fig. 1.78b). |
