1.Given simply supported beam with an overhang. The beam is 12 inches wide by 24 inches deep, and the slab is 6 inches deep. use a roof live load of 20 psf, and a concrete density of 150 pdf. the beams are spaced 15 feet apart. the total beam length is 30 feet, with 24 feet between supports and a 6 foot overhang. plot the shear and moment diagrams for the beam
2.A vane, 10 cm long and 8 cm in diameter, was pressed into soft clay at the bottom of a bore hole. Torque was applied and gradually increased 45 N-m when failure took place. Subsequently the vane rotated rapidly so as to completely remould the soil. The remoulded soil was sheared at a torque of 18 N-m. Calculate the chohesion of the clay in the natural and remoulded states and also the value of sensitivity
