Question

Item 2 Part A Consider the simply supported beam shown in (Figure 1) Suppose that P-13 kN, w= 7 kN/m. Point D is located just to the left of the 13-kN concentrated load. Followw the sign convention. Determine the internal normal force at point C. Express your answer to three significant figures and include the appropriate units. 0 NcValue Units Submit My Answers Give Up Figure 1 ot1 Part B Determine the internal shear force at point C. Express your answer to three significant figures and include the appropriate units. kN Submit My Answers Give Up 1.5 m 1.5 m-_ 1.5 m-1.5 m Incorrect; Try Again; 4 attempts remaining

Explanation / Answer

Calculate the reactions at the supports of a beam

AT C: Normal force= 0 (As there are no horzontal force on the beam)

Shear force =-11.5+13+(1.5*3.5/2) =4.125 KN

Bending moment = 11.5*4.5-13*3-(1.5*3.5/2) 1.5/3=11.4375KN.m

AT D: Normal force= 0 (As there are no horzontal force on the beam)

Shear force =-11.5

Bending moment = 11.5*1.5 =17.25 KN.m
