Why do levers have a greater mechanical efficiency than other simple machines do?
You can move a large load using a relatively small effort. http://www.deyes.sefton.sch.uk/technology/AS&Alevel/mechanical_systems.htm
What is the purpose of using a simple or compound machine?
The purpose of using simple or compound machines is to make tasks easier by amplifying or redirecting the force applied to them. These machines allow humans to accomplish tasks that would otherwise be difficult, time-consuming, or even impossible without them. Here are some specific purposes of using simple or compound machines: Mechanical Advantage: Simple and compound machines provide a mechanical advantage, allowing users to apply less force over a greater distance to achieve the same work output. This is especially useful when lifting heavy objects, moving loads, or performing repetitive tasks. Efficiency: Machines can improve efficiency by reducing the work required to perform a task. Machines can achieve greater output with less input energy by leveraging principles such as leverage, pulleys, gears, or inclined planes. Safety: Machines can enhance safety by minimizing the risk of injury or strain associated with manual labor. For example, using a lever or a pulley system to lift heavy objects can reduce the risk of back injuries. Automation: Compound machines, such as complex mechanical systems or industrial machinery, automate repetitive tasks, increasing productivity and freeing humans from performing mundane or dangerous work. Precision and Control: Machines can provide precise control over movements or processes, allowing for accurate manufacturing, construction, or other applications where precision is crucial. Overall, the purpose of using simple or compound machines is to enhance human capabilities, improve efficiency, and enable the accomplishment of tasks that would otherwise be challenging or impractical to perform manually.
What is the trade off of effort in using simple machines?
The simple machines - a lever for example - are usually designed so that you need less force. In compensation, you need to move the lever for a greater distance. This follows directly from the law of conservation of energy.
What simple machines were used to build the great wall of china?
Simple Machines allowed the builders of the Great Wall of China to build more quickly and efficiently. Machines such as levers and inclined planes allowed the amount of energy spent to do the work to be decreased. Other machines such as pulleys allowed objects to be transported up and down the wall with greater ease. Wedges were incorporated in the hammers that the Chinese used to pound the earth and all the materials of the Wall together.
What do all simple machines have in common?
all simple machines are alike in that they conserve the total amount of work done, but change the amount of force required to do that work by changing the distance over which that force must act.
Why do levers have a greater mechanical efficiency than simple machines?
The transmission lever is very simple and there is no friction.
The efficiency of the wedge is low because of?
friction or The mechanical advantage is greater for thinner wedges. However, the efficiency is low because of the large amount of friction.
Is a ideal machine has an efficiency of less than one equal to one greater than one?
ideal machines have mechanical efficeincy equal to 1 (100% efficient) since efficiency is the ratio of the power output to the power input
Why can't a pulley have a mechanical advantage greater than 1?
The mechanical advantage of a pulley can be greater than 1.The efficiency cannot but that is a different matter.

How can machines be changed?
People are developing new machines all the time. Sometimes they do things that earlier machines could not do, or they may do the same things but with greater efficiency, greater speed, less cost, and so forth. We always try to make our machines better.
The efficiency of gas exchange in the lungs of vertebrates is greater because of what?
The efficiency of gas exchange in the lungs of vertebrates is greater because it increases the lungs' internal surface area.
What does IMA stands for in physics?
IMA stands for "Ideal Mechanical Advantage" in physics. It is a measure of the mechanical advantage of a simple machine, such as a lever or pulley system, in the absence of friction. It is calculated by dividing the distance over which the input force is applied by the distance over which the output force is exerted. A higher IMA indicates a greater mechanical advantage of the simple machine.
Is energy input is greater than enrergy out put?
In machines, this is always the case, since the machine won't work at 100% efficiency.
Why do machines the less force to do the same amount of work?
Because machines allow force to be applied over a greater distance.
What is a coumpound machine?
A compound machine consists of two or more simple machines put together. In fact, most machines are compound machines. Compound machines can do more difficult jobs than simple machines alone. Their mechanical advantage is far greater, too. Some examples are a pair of scissors and a bicycle.
