Bumbers have shock absorbers on them to absorb the shock of a minor impact (5mph) without causing significant damage to the car or the object hit. So, if you backed into a concrete wall while parking, the bumper would move with the shock absorbers - you might get a scuff on the paint; but if there was no shock absorber, the bumper or the mounting brackets would get bent (or the wall would break).

What is a shock load?
Shock load is a machining term. Shock load is when a sudden intense force is placed on the parts of a machine. The machine often cannot handle the pressure.
An open coiled wire spring that cushions or absorbs the force of a part pressed against it and then?
This type of spring is commonly known as a compression spring. It is designed to compress under a load and absorb energy, providing cushioning or shock absorption in various applications such as automotive suspension systems, mattresses, and industrial machinery. The spring returns to its original shape once the load is removed, making it an efficient component for absorbing force.
What happens to a spring when a load is applied to it?
You compress it Well, it ALL depends on how hard you push down on the spring.
What is the purpose of a spring washer?
The purpose of a spring washer is to offer spring force, sustain a load, or provide a method to absorb shock. This is achieved through the design of the washer of which its namesake describes. Much like the shocks of a car the spring washer performs the same duty at a much smaller level.
A spring that stretches 5.0 cm when a load of 11 N is suspended from it how much will the spring stretch if an identical spring supports the load?
since the springs share the load the stretch displacement is load divided by the sum of the spring constants. If the springs are identical the stretch is one half of the stretch with only the one spring, or 2.5 cm
What is spring-stiffness?
Spring stiffness is a property that relates load to deflection. Let k = stiffness and P = load and x = deflection, then P = kx The stiffer the spring, k, the smaller the deflection under a constant load. k can be measured for springs and otherdevices, such as beams, with simple load deflection devices or machines that measure deflection as function of laod
How do shock absorbers absorb shock?
Cars absorb shock by use of their suspension system. This is made up of both the springs and shock absorbers / dampers. The suspension system allows the wheels to move up and down separately to the car body / chassis when a car goes over a bump or pothole. When this happens the springs compress or stretch and so help resist the displacement and because of the way a spring works, the greater the displacement the more the spring resists it. However to stop the spring "springing" back into it's original place too quickly and to prevent it vibrating and shaking the car repeatedly (which would be very uncomfortable and also make safe control of the vehicle much more difficult) they are also fitted with shock absorbers or dampers. These are cylinders filled with a viscous fluid with a piston inside them. The piston is porous and permeable and so can pass through the fluid but the fluid resists the motion. As the velocity of the motion increases so to does the amount of resistance. This stops the spring being forced to move too quickly when hitting a bump, it also stops it rebounding to quickly afterwards and stops the spring from oscillating backwards and forwards. Essentially it dampens the movement - hence the use of the name damper.
What does preload mean on motorcycle shocks?
Preloaded means you would make an adjustment that would put a load on the shock, spring with a coil over. This would stiffen the shock and would shorten the available travel causing a rougher ride. This is needed if you are riding 2 up to keep the rear tire from rubbing the fender when the bike is under heavy acceleration or running turns at a faster speed. If you are preloading a coil over shock the adjustment is towards the bottom of the spring. Make sure both sides are set in same position.
What is the difference between shock loading and dynamic loading of cranes?
A dynamic load arises from the acceleration or deceleration of a "static" load (mass). A shock load occurs when this acceleration or deceleration is very large and the the time frame is very short.
How do you define hookes' law?
In mechanics, and physics, Hooke's law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load added to it as long as this load does not exceed the elastic limit. So if you keep inside the load limit of the spring, the spring will return to it's original shape. As soon as you exceed that load the spring will stretch and not return to it's original shape
What are the stress involved in the open coiled helical spring subjected to an axial load?
When an open coiled helical spring is subjected to an axial load, it experiences both shear and normal stresses. The primary stress is shear stress, which arises due to the torsional effects of the load on the coil. Additionally, there can be normal stress induced by the axial load, particularly if the spring is compressed or extended. The combined effect of these stresses can affect the spring's performance and durability.
