The following 3 beams are the same length and each support a total load of 1000lbs. Comparing the 3 beams, which one has the largest: Internal bending moment? Beam A Beam B Beam C 1'-6" 5'-0" w = 100lb/ft P = 500lb 10'-0" P = 1000lb 7'-0" Beam A Beam B Beam C They are all the same. 5'-0" P = 500lb 1'-6"

1.13 The section shown in Fig. 3.34 represents a beam in a structure containing prefabricated elements. The total width and total depth are limited to 350mm and 530mm respectively. Tension reinforcement used is four $28 bars. Using fe-28 MP and fy=420 MPa, determine the design moment strength of the section. 65 465 100 125 100 350 125 8 = 0.003 N.A. + 0.85fc T=A,fy T z=d-y

Please answer with a complete solution. Thank you! The roof truss is supported by a hinge at A and a horizontal roller support at B. The wind loads are perpendicular to BC. Determine the reactions at A and B.

The answer is between 18.25 and 20.25
