If the difference of height between two points is 1 m and the slope distance between them is 100 m, then accuracy of slope correction determination could be 1 in 1, 00, 000, provided the heights are measured with an accuracy of
Consider the following statements regarding a simply supported beam subjected to a uniformly distributed load over the entire span : 1. The bending moment is maximum at the central position. 2. The shear force is zero at the central position. 3. The slope is maximum at the middle position. Of these statements :
