What is absolute maximum bending moment in influence line diagram?
The absolute maximum bending moment in an influence line diagram represents the greatest bending moment that can occur at a specific location in a structural member due to a moving load. This moment is determined by analyzing the influence line, which illustrates how the bending moment varies as a point load moves across the structure. The peak value of the bending moment on the influence line indicates the worst-case scenario for design and safety considerations. It is essential for engineers to calculate this value to ensure structural integrity under varying load conditions.
How do you design bending moment envelope?
To design a bending moment envelope, begin by determining the loading conditions and support reactions for the structural member using structural analysis methods. Next, calculate the bending moments at critical sections along the member's length under various loading scenarios, such as dead loads, live loads, and environmental factors. Plot the maximum and minimum bending moments on a graph to visualize the envelope, which represents the range of moments that the structure will experience. Finally, use this envelope to ensure that the member's design conforms to strength and serviceability criteria.
Why you study about shear force and bending moment?
The importance of shear force and bending moment diagram in mechanics lies in structural design and in deflection of beams.
What do you mean bu equivalent shear force and equivalent bending moment?
MAXIMUM SHEAR force bending moment is zero shear force change inside is called bending moment

a simple definition " IT'S A COUPLE OF FORCE HAVING EQUAL MAGNITUDE BUT OPPOSITE IN DIRECTION & HAVING VERY LESS DISTANCE BETWEEN THEM"

What is external bending moment?
External bending moment is a force applied to a structural member that causes it to bend. It results in a combination of tensile and compressive stresses on the material of the member. External bending moments are important considerations in the design of beams and other structural elements to ensure their ability to resist bending and carry loads.

If the maximum bending is maximumat a point what about the deflection?
If the maximum bending moment occurs at a point, then the corresponding deflection will also be maximum at that point. This is because the deflection of a beam is directly influenced by the bending moment acting on it. So, wherever the bending moment is greatest, the deflection will also be greatest.

When a cantilever is loaded with udl the maximum bending moment occurs at?
When a cantilever beam is loaded with a Uniformly Distributed Load (UDL), the maximum bending moment occurs at the fixed support or the point of fixation. In other words, the point where the cantilever is attached to the wall or the ground experiences the highest bending moment. A cantilever beam is a structural element that is fixed at one end and free at the other end. When a UDL is applied to the free end of the cantilever, the load is distributed uniformly along the length of the beam. As a result, the bending moment gradually increases from zero at the free end to its maximum value at the fixed support. The bending moment at any section along the cantilever can be calculated using the following formula for a UDL: Bending Moment (M) = (UDL × distance from support) × (length of the cantilever - distance from support) At the fixed support, the distance from the support is zero, which means that the bending moment at that point is: Maximum Bending Moment (Mmax) = UDL × length of the cantilever Therefore, the maximum bending moment in a cantilever beam loaded with a UDL occurs at the fixed support. This information is essential for designing and analyzing cantilever structures to ensure they can withstand the applied loads without failure.

MAXIMUM SHEAR force bending moment is zero shear force change inside is called bending moment
What is absolute maximum bending moment?
bending moment varies with the distance & the load carried by the beam. And also there is a hogging behavior and a sagging behavior occurs in the beam. According to the sign convention hogging and sagging bears opposite signs.(- & +). So if we are asked to find the maximum bending moment whether it is sagging or hogging we should consider the maximum value without considering the sign. That value is called maximum absolute bending moment.
What is Point of contraflexure?
A point of contra flexure occurs where the bending moment in a beam changes its sign (i.e. from +ve to -ve or -ve to +ve) So, obviously at the point of contraflexure the bending moment is zero. But note that the bending moment can be zero without changing its sign. So, at the point of contraflexure the bending moment has to be zero and the bending moment must change its sign as well.
What is the difference between deflection and bending?
Bending moment With "bending" you really mean the bending moment. The bending moment in an inner stress within a member (usually beam) that allows it to carry a load. The bending moment doesn't say anything about how much a beam would actually bend (deflect). Deflection Deflection measures the actual change in a material you could call "bending." It measures the physical displacement of a member under a load.
What is the significance of the internal bending moment in structural analysis and design?
The internal bending moment in structural analysis and design is significant because it helps engineers understand how forces are distributed within a structure. By analyzing the bending moment, engineers can determine the strength and stability of a structure, ensuring it can support the loads it is designed for. This information is crucial for designing safe and efficient structures.
What is difference between moment and bending moment?
A moment is a vector quantity that measures the tendency of a force to rotate an object around a specific point or axis. It is calculated as the force applied multiplied by the distance from the point of rotation. Bending moment, on the other hand, is a specific type of moment that occurs in beams or other structural elements subjected to bending loads. It is the algebraic sum of the moments about a particular point along the length of the beam and indicates the bending behavior of the material.
