Question

THEORETICAL CALCULATION Support Reactions. If P= N and the L. is _mm: a free body diagram of entire beam is shown in Fig. 2 (a) +F;=0; -P+A,+C, =0 L/2 +M = 0; - P(1/2)+C,L=0 L/2 YU L C Region AB AO Shear and Moment Functions. A frec-body diagram of the left segment of the beam is shown in Fig 2 (b). Applying the two equations of equilibrium yields +1 F, =0, V=P/2 ...) cew+M=0; M =(Px)/2 ...(2) + F = 0; P/2-P-1=0 V=-(P/2) ...(3) Cow+M=0, M+P(x -L/2)-(Px/2)=0 P/2 Region BC: x M = (1-x) (4) 1/2 (b) JP Shear and Moment Diagrams. The shear and moment diagrams as shown in Fig. 2 (c) are obtained by plotting Eqs. 1,2,3 and 3. The maximum interna moment in the heam occurs at the center as shown on the hending moment diagram The value of x = L/2 represents the point on the beam where the maximum internal moment occurs since the slope V=dMdx -0. 个 P/2 P/2 P/2 M ---- Section Property. The moment of inertia about the neutral- axis is calculated as follows: -PI2 PL Page 3 CHAPY Maximum Bending Stress M 07 My M. 1,

By assuming P and L calculate the moment of inertia (I1,I2, and I3) and the maximum bending stress as it mentioned below

Answer 1

please provide the cross section so that i can calculate moment of inertia of each section..THANK YOU
