Extracted text: (a) Construct the influence line (IL) for shear Vp at point D of the beam ADBC as shown below. Also (b) determine the maximum negative shear Vp due to simultaneous application of uniform load of intensity 12 k/ft., which can act over any part and any extent of the beam, and a concentrated load of 6 k. VD [Hint: The shape of IL for shear (V) will look similar to the sketch D. B C 10 ft. 5 ft. 8 ft.
