Humans were constructing ramps for various purposes long before written records existed. A 3.7-mile paved ramp constructed by the ancient Greeks was used to drag ships across the Isthmus of Corinth. Earthen ramps were used to allow an army besieging a city to storm the defenses, and there is some evidence that the builders of Stonehenge relied on ramps to place the massive stones. Many Egyptologists believe that workers used ramps when building the pyramids. Although technology has changed a great deal since the construction of the pyramids and Stonehenge, ramps are still commonplace features in the modern world.
What Are the Advantages of Ramps?
Ramps make it easier to move loads from a higher point to a lower point or from a lower point to a higher point. Moving a load up a ramp requires less force than would be required to lift it

For example, the ramps in a parking garage allow vehicles to drive from one level to another, while ramps in manufacturing facilities allow forklifts to go from the production floor to a separate warehouse.
Considerations for Ramps
The first point to consider is slope of the ramp. Slope is calculated by finding the difference in height between the two ends of the ramp and then dividing that number by the horizontal length of the ramp. Smaller slopes require less force to move a load than would be required to move the same load on a ramp with a greater slope.
Another consideration is the texture of the ramp. A rough concrete ramp or one that contains cracks will make it harder to move the load, while a smooth, level ramp will make it easier.
When planning a loading ramp, it is important to consider the weight of the loads that will be placed on the ramp. For example, a loading ramp designed to allow trucks to back up to the dock will need to be stronger than a loading ramp that supports only forklift
Since there are so many options on the market, take several options in consideration and choose the best one according to you specific requirements. Gather all information, so you can compare in-floor with fold-out ramps and choose one according to the conditions you will be using it. If you're based in an area where it rains and snows a lot, an in-floor lift may be solution to helping you keep your interior clean. Fold-out lift may be a better option if you live in area with lots of curbs and hills.

The first permanent stone fortifications was built in Jericho. They constructed the building using roughly shaped stones laid without mortar (Kleiner, 24). Once Jericho’s inhabitants left their site, a different group of people came to settle there. They used different techniques, “…established a farming community of rectangular mud-brick houses on stone foundations with plastered and painted floors and walls” (Kleiner, 25). The megalithic tomb in Ireland was built in the form of a passage grave. “At Newgrandge, the huge megaliths forming the vaulted passage and the dome are held in place by their own weight without mortar, each stone countering the thrust o neighboring stones. Decorating some of the megaliths are incised spirals and other motifs” (Kleiner, 27). The main chamber used early examples of corralled vaulting and in addition the Newgrandge tomb illuminates sunlight through the passage and the burial chamber during the winter solstice. Nearing the end of the fourth millennium BCE, Neolithic civilization had spread in every diffraction even to small remote areas. “…Hagar Quim is one of many constructed on Malta between 3200 and 2500 BCE” (Kleiner, 27).The builders of Malta constructed the temple by pilling cut stone blocks very carefully in stacked horizontal rows. “To construct the doorways at Hagar Qim, the builders employed the post-and-lintel system in which two upright stones
Stonehenge took almost one thousand five hundred years to build. According to claims by anthropology.msu.edu, “The construction of Stonehenge began with the outer ring which consisted of sarsen sandstone slabs excavated from local quarries in England’s Salisbury Plain, while the inner ring was being built with smaller Bluestone rocks that scientists have tracked back to the Preseli Hills in Wales, nearly two-hundred miles away from the construction site of Stonehenge”(Stonehenge: the Ancient Alien Theory). Therefore, researchers have been questioning how those neolithic people were able to move four tons worth of boulders over such a great distance, especially considering that this monument was constructed around five thousand years ago. Von Däniken and other theorists believe that the aliens were involved in the construction of Stonehenge, and many other pieces of history as

Mycenaean sites employed Cyclopean masonry as the means of building their fortification walls. Cyclopean masonry was used at all of the fortified Mycenaean sites and it is built by using large flat-surfaced blocks with smaller stones fitted in the cracks (Dickinson, 1994). The walls would have two faces and the space would then be filled with rubble. It is believed the fortification walls were not truly meant to fortify a citadel, but were a means of displaying the city’s wealth (Loader, 1995). According to Loader (1995) Cyclopean masonry was a distinct style of Greece. The use of corbelled vaults was also common. The Mycenaeans did not know the principle of the true arch so they stacked blocks on top of one another and pushed the ends of both sides in to create a sort of vault before creating a smooth interior surface. This method requires heavy weight on the backs of the blocks used to make the vault to avoid a collapse.
Archeologists suggest that the large stones used in building the pyramids were transported by rolling them over logs or a wet, slippery, clay surface. These methods may have been effective in moving the blocks close to the building site, but do not explain how the massive bricks, weighing as much as a Ford F250 truck, were lifted on top of each other.
The engineering discoveries of ancient Rome have played a key role in the history of architecture and engineering. Many of Rome’s roadways, bridges, and aqueducts have been in use from the first century until the twentieth century. Many American buildings have used the Roman dome. Several major structures from early Rome still stand, including the Collosseum. These remnants of feats of Roman engineering stand as a monument to the ability of ancient Roman builders.
Explanation: The height of the ramp affects the speed and distance the ball rolls because the higher the ramp, the more gravitational potential energy the ball has, which is then transferred to kinetic energy. The length of the ramp affects the gradient, which affects the speed and distance the ball rolls. The surface of the ramp and marble cause friction, which affects the speed and distance the ball rolls. The weight and size of the marble affect the gravitational potential energy and the amount of friction, which affects the speed and distance the ball rolls.

This class has examined the various accomplishments of ancient Rome, many that have been carried on throughout time and influenced numerous cultures around the world. Amongst those accomplishments were the development of concrete and the utilization of arches. This paper will examine the Roman development of both concrete and the infamous concrete arch that is utilized in many modern day structures today.
We did not have a specific place on the ramp at where we would drop the mass pieces onto the trolley. We just dropped them anywhere on the ramp. The position of the collisions was different for all three trials which might have affected the results because the distance after the collisions was different for every collision. There was no consistency.
