Maximum Moment if an additional 50 kN concentrated load is acting at 2 m from the right support. b. Moment of Inertia of the section about its neutral axis c. Maximum Bending stress if an additional 50 kN concentrated load is acting at 2 m from the right support. 210 mm 24 mm 15 mm 230 mm A B 24 mm

The cross-sectional area of a wide-flange I-beam has the dimensions shown. Obtain a close approximation to the handbook value of Ix = 654 in.4 by treating the section as being composed of three rectangles. 0.380" 7.073" ·x 16.25" Answer: I = i k 10.628" in.4

PLEASE BOX THE FINAL ANSWER, A LOT OF SOLVER'S SOLUTIONS ARE MESSY. Please give me explanation

Can you please explain clearly on how to calculate that maximum bending moment.

The shear stress and the polar moment of inertia are inversely proportional. Select one: a. False b. True

A beam having a tee-shaped cross section is subjected to equal 18 kN-m bending moments, as shown. Assume bf = 125 mm, tf = 25 mm, d = 185 mm, tw = 20 mm. The cross-sectional dimensions of the beam are also shown. a.Determine  the centroid location (measured upward from the bottom), in mm rounded to the nearest tenths. b.Determine  the moment of inertia about the z axis. Express your answer in (106) mm4 rounded to three significant figures. c. Determine  the controlling section modulus about the z axis. Express your answer in (103) mm3 rounded to three significant figures. d. Determine  the controlling section modulus about the z axis. Express your answer in (103) mm3 rounded to three significant figures.

Given P = 1.5 kN, M = 1.4 kN.m (clockwise), 0 = 55°, and a = 2 m, what is the resultant internal normal force acting on the cross section at point A? M A
