Where the bending moment is maximum?
Explanation: Let w be load intensity, V be the shear force and M be the bending moment. Bending moment is maximum where shear force is zero or its changes sign (positive to negative or vice-versa).
Which section is most economical and preferred for resisting bending moment?
I sections (rolled and built-up) are most efficient and economical shapes. I section with cover plates are provided when large section modulus is required. Generally, ISLB or ISMB are provided in such cases.
Which cross section has maximum stiffness?
This is done by using sectional shapes for which most of the sectional area is remote from the neutral axis. For example, a beam of square cross-section is stiffer than a circular beam with the same area, since a circle has a larger proportion of the section near the neutral axis.
Where bending stress is maximum?
The maximum bending stress occurs at the top surface of the die, and its location is corresponding to the inner bumps of the bottom die. The deflection of the beam is proportional to the bending moment, which is also proportional to the bending force.
What is the maximum bending moment for the simply supported beam carrying central point load shown below?
What is the maximum bending moment for simply supported beam carrying a point load “W” kN at its centre? Explanation: We know that in simply supported beams the maximum BM occurs at the central span. Moment at C = W/2 × l/2 = Wl/ 4 kNm (Sagging). 6.
Which of the these is the best cross section for resisting bending of the longitudinal member of vehicle frame?
Box section is equally capable in resisting BM. I- section is the most efficient one. Reason being: For same area it gives much higher moment of inertia which results in stiff section and hence deflection is very less.
What does maximum bending stress mean?
The maximum stress occurs at the surface of the beam farthest from the neutral axis. In order to calculate maximum surface stress, you must know the bending moment, the distance from the neutral axis to the outer surface where the maximum stress occurs and the moment of inertia.
What is the maximum bending stress in beams?
The maximum bending stress occurs at the extreme fiber of the beam and is calculated as: where c is the centroidal distance of the cross section (the distance from the centroid to the extreme fiber).
