How do beam bridges support weight or load on them?
Instead of pushing straight down, the load of an arch bridge is carried outward along the curve of the arch to the supports at each end. The weight is transferred to the supports at either end.
What is a critcal load?
A critical load refers to the maximum amount of stress or force that a material or structure can withstand without experiencing failure or significant deformation. In engineering and materials science, it is crucial for determining the safety and performance limits of structures like bridges, buildings, and mechanical components. Understanding critical loads helps in designing safe and efficient structures by ensuring they can support expected loads without compromising integrity.
What is shear force?
Shear force is an internal force in any material which is usually caused by any external force acting perpendicular to the material, or a force which has a component acting tangent to the material. Take a ruler or a block of wood, and put it in table surface. Pushing the ruler or the block of wood in the downwards direction, will create a shear force inside the block of wood or the ruler. Since you are creating a force that's perpendicular to the material. The bigger force you apply to the ruler or the block of wood, the higher the shear force the material is going to experience in general. Please note shear force is an internal force, and in the block of wood or the ruler in this case, the shear force can vary at different point in the material. You can also draw a shear force diagram which represent how much shear force a material is experiencing at different point.
How do bridges stay up?
A bridge has three things to complete the foundation to keep it from collapsing. They are called spread footings, caissons and piles. It also has the deck itself. +++ All these components are also very carefully designed to withstand the various stresses that they will bear in service.
What is the difference between the processes of stamping and extrusion?
Stamping involves a force applied to a die that removes a section of material, typically thin. Extrusion is a process where a force is applied to a fluid material which is pushed through a die creating the rough final form. Extrusion is much less wasteful in most circumstances.
Do electromagnets stay charged?
Electromagnets do not stay charged. They work by maintaining and creating a field around an object. If the force is broken then the magnet will go weak as well.
What scientific force is primarily responsible for maintaining control of your vehicle?
friction
Why did this new IT become a major force in creating a paperless revolution?
Why did this new IT becomes a major force in creating a "paperless revolution"?
How do you get Adam's laser on shining force?
It happens when you get a critical
How do you get a critical on fruit ninja frenzy?
you can do a critical hit by cutting the fruit's weak spot with full force
Critical factor that determines force of heart beat?
The critical factor that determines the force of a heartbeat is the degree of stretch of the cardiac muscle just before it contracts. The force of the heart beat can also be called the stroke.
Which of following establishes the overarching policy for the Critical Asset Risk Management Program (CARM) for the Air Force?
AFPD 10-24, Air Force Critical Infrastructure Program (CIP)
What is the role of actomyosin?
Actomyosin is a complex formed by the interaction between actin and myosin proteins. It plays a critical role in muscle contraction by creating the force necessary for muscle movement. Actomyosin also functions in cell motility, cytokinesis, and various cellular processes requiring mechanical force generation.
The most important force operating in a tornado?
The most important force operating in a tornado is the strong updraft of air that can reach incredibly high speeds, causing rotation and lifting debris into the air. This updraft is responsible for creating and maintaining the funnel-shaped cloud and the intense winds associated with tornadoes.
What is critical acceleration?
Critical acceleration is the minimum acceleration required to cause an object to start moving or sliding on a surface. It is the point at which the frictional force between the object and the surface is overcome by the applied force.
