4. If the maximum shear stress at the end of a simply supported R.C.C. beam of 6 m effective span is 10 kg/cm2, the share stirrups are provided for a distance x from either end where x is
5. An R.C.C. beam of 25 cm width and 50 cm effective depth has a clear span of 6 metres and carries a U.D.L. of 3000 kg/m inclusive of its self weight. If the lever arm constant for the section is 0.865, the maximum intensity of shear stress, is
6. A pile of length L carrying a uniformly distributed load W per metre length is suspended at two points, the maximum, B.M. at the centre of the pile or at the points of suspension, is
7. If p1 is the vertical intensity of pressure at a depth h on a block of earth weighing w per unit volume and the angle of repose ?, the lateral intensity of pressure p2 is
