In a cantilever beam point load is applied on free end where failure will occur?

The maximum tensile stress will occur at the fixed end on the side the load is applied to. An equal compressive stress will occur on the opposite side. Shear stress is typically neglected because it is relatively small compared to the stresses due to the bending moment. Stress S is found using:
S = M*c/I
where M is the moment at the point in question (maximum at the fixed end), I is the moment of inertia of the beam/tube, and c is the distance from the centroid/centerline to the point in question. Again the maximum stress occurs farthest from the load and farthest from the centerline/centroid (I don't recall which one is used, but they're the same if the beam/tube is symmetrical).
Moment is simple,
M = P * L
where P is the load perpendicular to the beam in units of force, and L is the length from the load to the point in question or fixed end.
c is also simple, for a 1"x1" box tube c equal 1" divided by 2. So c = 0.5".
The moment of inertia I will depend on the shape of the tube or beam and can be easily calculated using the appropriate formula from a table.

When a load is applied on a fastener until it breaks the load at which it breaks is called the?
It could be called the 'point of failure.'
How do you calculate the bending moment for a cantilever slab?
Max BM for a cantilever would be @ the point of support and would be equal to WL/2 where W=wL Max BM for a cantilever would be @ the point of support and would be equal to WL/2 where W=wL Edit- As said above the max bending moment for a cantilever will be at the supportFor a distributed load M=wL2/2 where w=the fractured distributed load and L= the leaver arm For a point loadM=PL where P=the point load and L= the leaver arm *Having a cantilever means you will have reinforcing in the top of the beam/slab till a distance after the beam

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.

Failure to yield the right of way in Virginia?
that's a moving violation. if an injury has occured than a point may be applied.

What is the difference between a beam fixed at both ends and a cantilever beam?
A cantilever has only one end or point fixed; this is an obvious difference between having two points or both ends fixed. The nature of bending moment is same throughout the span in the case of a cantilever beam whereas a fixed beam has both types of nature, i.e. sagging as well as hogging.
At what point does a bridge break?
failure
What is the definition of a propped cantilever beam?
A beam with a built in support at one side (ie no rotation about or translation in the x, y, z direction) and a point support at the other (ie no translation in the x, y, z direction but rotation about the z direction)
