A groyne helps to trap and accumulate sediment along the shore, reducing erosion and stabilizing the beach. It can also create calmer waters in the area behind it, providing a safer environment for swimmers and recreational activities.
Mechanical advantage is determined by physical measurement of the input and output forces and takes into account energy loss due to deflection, friction, and wear. The ideal mechanical advantage, meanwhile, is the mechanical advantage of a device with the assumption that its components do not flex, there is no friction, and there is no wear.
In a mechanical advantage system, the force is multiplied by the factor of the mechanical advantage. The formula for mechanical advantage is MA = output force / input force. This means the force can be multiplied by the mechanical advantage value.
Time can be used to measure mechanical advantage by comparing the time taken to perform a task with and without a mechanical advantage device. If a mechanical advantage device reduces the time required to complete a task, it indicates that the device has increased the efficiency of the task, thereby providing mechanical advantage.
The amount by which a machine multiplies an input force is called mechanical advantage. It is calculated by dividing the output force by the input force.

A build-up, which is often accompanied by accelerated erosion of the downdrift beach, which receives little or no sand from longshore drift. (This is known as terminal groyne syndrome, as it occurs after the terminal groyne in a group of groynes).
Groyne
A Groyne can cost up to about £5000. Hope This Helps x GEOG 2 BOOKS FOR SCHOOLS x
A groyne is a hydraulic structure that is used to interrupt water flow and to keep sediment from moving. Groynes can cost up to $770,000.
a single groyne cost about £5,000 per metre http://www.mjanderson.chislehurst.btinternet.co.uk/coastseadefence.htm this is where find more of the cost of sea defences :D

A beach groyne works when you put a groyne on the water (usually made of timber, bamboo, or other materials), the only source for a groyne is so that the whole beach/island doesn't "wash away" and all of it's sand get washed off into the ocean.
The groyne has many features that make it useful. Gyrones can be designed however a person wants it to be designed, which makes it as permeable or nonpermeable as they want.
The cost of a groyne per meter can vary significantly depending on various factors such as the type of material used, the size and design of the groyne, the location, and the construction method. On average, the cost can range from $500 to $2000 per meter for a typical timber or rock groyne. More durable and long-lasting materials like concrete or steel may cost more, potentially exceeding $3000 per meter. It is essential to consult with experts and obtain quotes from contractors to get an accurate estimate for a specific groyne project.
A groyne is a structure which is built at least partially underwater to inhibit water flow and control the movement of sediment. The purpose of a groin at the beach is either to create more beach or to prevent the erosion of an existing beach.
