Derive the shear and moment function and use it to draw the shear and moment diagram of the beam shown. Use the given reference points. メ」 20KYM GOKN 10KN/m 10KN/m 40KN-M

The 21m long beam is subjected to the forces and moments shown in the attached image. Find the internal normal force (N), internal shear (V) and internal moment (M) at points A and B.

Example An experimental device imparts 700-mm 900 mm a force of magni- moments of the force F about point O and about point B. Finally, locate, from the base at O, a point C on the ground where the force imparts zero moment. 300 mm A 3050 mm

A two-span, continuous wood girder (E = 2,000 ksi) supports a roof patio structure (part (a) of the figure). A uniform load of intensity q acts on the girder, and each span is of length 8 ft. The girder is made up using two 2 x 8 wood members (part (b) of the figure). a q= 17.0 lb/ft -8 ft (a) B 8 ft 41 8 in. 2 in. 2 in. Section a-a (b) 000 8 in. Ignore the weight of the beam. Use the nominal dimensions of the beam in your calculations. (Solve by the method of superposition. The beam has constant flexural rigidity EI, unless otherwise stated.) (a) Find the reactions at A, B, and C. (Enter your answers in lb. Round your answer for Rg to at least one decimal place. Use the statics sign convention.) lb RA RB = lb RC lb
