Maximum shear acting on a point

In summary, when finding the maximum positive shear, we only need to consider three cases. This is because the maximum shear will only occur when a certain load is applied to point B. This applies to beam problems, not soil mechanics.

Homework Statement


Why we need to consider only 3 cases when we want to find the max positive shear ?

Homework Equations

The Attempt at a Solution


IMO , We know that the max shear will only occur when the 67.5kN act on B , am i right ? There is no need to consider 3 different cases ...Or my concept is incorrect ? If so , can anyone show me the example where the max shear will occur at B although the max concentrated load doesn't act on the particular point ?

Update : Why the max shear will only occur at B when the certain load act on it ? Can someone explain about it ?

@Chestermiller , can you help ? I think you are the only one in this forum who knows soil mechanics

This is not a soil mechanics problem. It is a beam problem.

FAQ: Maximum shear acting on a point

What is maximum shear acting on a point?

Maximum shear acting on a point refers to the maximum force that is applied on a specific point of an object. It is a measure of the internal forces within a material that causes it to deform or break.

How is maximum shear acting on a point calculated?

The maximum shear acting on a point is calculated by taking the derivative of the shear force diagram at the point of interest. It can also be calculated by dividing the maximum bending moment by the distance from the point to the neutral axis.

What factors can affect the maximum shear acting on a point?

The maximum shear acting on a point can be affected by various factors such as the shape and size of the object, the direction and magnitude of the applied force, and the type of material the object is made of.

Why is it important to consider maximum shear acting on a point in engineering?

Understanding the maximum shear acting on a point is crucial in engineering as it helps determine the strength and stability of a structure. It also helps engineers determine the appropriate materials and design to ensure the safety and functionality of the structure.

How can maximum shear acting on a point be reduced?

To reduce the maximum shear acting on a point, engineers can use techniques such as reinforcing the structure with additional materials, changing the design of the structure, or redistributing the load on the structure to other points.
