Note: V, M diagrams should be drawn below the complete fbd of the beam and they should be | completely labeled with all the main values, slopes of inclined lines and degrees of curves P1 (7-79 mod) A beam is supported by a roller and a pin as shown. The 200 lb.ft couple moment acts at the midpoint of AB and the 300 lb.ft couple moment acts at the rightmost point of the beam. a) Determine the reactions at the supports b) Complete the fbd of the beam on the blank graphs shown on the following pages and draw the V and M diagrams below it using a scale of 1 division = 25 lb for the V diagram and 1 division 25 lb.ft for the M-diagram c) Determine the maximum and minimum internal shear and bending moment and their locations in the beam. 300 lb 100 lb/ft 300rb 300 lb-ft- 200 lb-ft B +1- -1 ft 4 ft 2' 7-79(mod) 2' 2001b. 100 lb/st 300lb.ft beam Vid M-diogrom
