Ancient cultures in the past have used simple machines to decrease the amount of force needed to build large structures. Simple machines were created to make work easier by changing force‚ distance‚ or direction. The six simple machines are inclined plane‚ wedge‚ screw‚ lever‚ wheel and axle‚ and pulley. With the help of these machines different tribes and groups have created many common structures we know today. Simple machines have changed society in many ways and lead to the creations of famous

that Egyptians had used levers in the past? In Ancient Egypt‚ Egyptians had moved heavy objects with levers and inclined planes. Egyptians had used the equal arm of the lever to balance objects. Levers can help people lift heavy objects in larger distances using less effort applied. Levers can be used to make our everyday lives much easier. Some levers may include objects that you already use such as a scissor or a baseball bat. There are three classes of levers‚ these levers include the first class

Balancing the Load: The See-Saw as a Simple Machine Introduction The see-saw is not just a playground toy‚ it is an example of a simple machine. In physics‚ simple machines are tools that make it easier to do work. A lever is an example of a simple machine. A lever is a straight rod or board that pivots on a stationary point called a pivot point or a fulcrum. Levers are often used to lift heavy loads. A see-saw‚ a shovel‚ and a wheelbarrow are all examples of levers. Abstract Have you ever tried

What simple machines did you incorporate into your nifty lifting machine? 1. In the nifty lifting machine Kenny‚ Kaylee and I used three simple machines. We used a pulley system as our first simple machine. The pulleys are what allowed pulling the 600 gram can up the five centimeters. My group also used a wheel and axle‚ which is the crank that we used to pull up the cans. The wheel is the gear and the axle is the dowel rod we used to tie the rope around. Then we used a wedge to stop the gear on

1. What are the two types of friction that affect the performance of your vehicle? The first type of friction that affects the mousetrap car is called rolling friction. This type of friction occurs in between the wheels of the car and the surface of the ground it moves on. The second type is called the sliding friction which occurs in between the axles and the brackets. 2. What problems related to friction did you encounter and how did you solve them? We noticed that at times the car would

The trebuchet is a large machine of the trebuchet family formerly used as a siege weapon and now for history reenactment‚ recreational or engineering purposes. It was formerly one of the most powerful weapons in history‚ being able to fire a projectile to a distance of up to three hundred yards accurately. It consists of a lever arm laid across a supporting crossbeam (the fulcrum)‚ a heavy counterweight on one end‚ and a sling on the other. The sling would hold the load (projectile) during battle
