When you use a lever to lift a rock is the output force is represented by the amount of force you apply to the end of the lever?
What you do to your end of the lever is the INPUT force.The OUTPUT force is what happens down there under the rock.How to decide ? Try this:The OUTPUT is the RESULT of all the tools, equipment, resources,knowledge, tricks, and machinery you have, and how you use them.
How is it possible for a small force on one side of a lever to balance a large force on the other side?
the weight is put on the angle of the lever not the small force pushing it down
What is the amount of force with which gravity pulls down an object?
The amount of force which gravity pulls down an object is called its weight.
Which fulcrum location required us to push down the lever the least to lift the load?
The fulcrum should be as far as possible from the effort to minimise the force needed. It should also be as close to the load as possible.
Which is the simple lever which helps to change the direction of a force?
A first degree lever, with the fulcrum between the force and the load, will change the direction of the force. Think of an adult on the ground pushing down on a see-saw to lift a child on the other end up into the air.

How is a single fixed lever different from a first class lever?
In a single fixed pulley, you pull (apply force) straight down (pull down). In a first-class lever you push up (apply force) , but not push.
How is it possible for a small force on one side of a lever to balance a large force on the other side?
the weight is put on the angle of the lever not the small force pushing it down
Is a force a lever?
No. A lever is a simple machine that redirects and multiplies the force applied to it. You press down on one end and whatever is on the other end goes up.
How does a lever increase the mechanical advantage?
It has to do with a type of force called torque. When you push down on a lever, the force you push with is multiplied by the length of the lever to produce a torque. If you have a very long lever, then you are multiplying your pushing force by a big number and can produce a big torque. It's an easy way to get a large force with little effort.
What is the amount of force with which gravity pulls down an object?
The amount of force which gravity pulls down an object is called its weight.
Why does force and torque vary as a joint moves through a range of motion?
torque is lever length * force normal to lever end example: 1 metre horizontal lever with 10 kg at end (force = m*g = 10 * 9.8 = 98 n vertically down) while the lever is horizontal, the force is normal (at 90 deg.) to it, so the torque is 1 * 98 = 98 n - m say the lever rotates down 45 deg. the force is still vertically down , but the component of the force now acting normal to the lever will be: sin 45 deg. * 98 = 0.707 * 98 = 69.3 newtons, so the torque is now 1 *69.3 = 69.3 n - m
Where the brake levers apply force in a bicycle?
Well, the lever will apply a force to a linkage, connecting the lever to the actual brake. Then the force will travel through the linkage, down to the brake. In the brake, the force will be used to pinch a moving surface between two stationary surfaces, and the friction generated there will slow the bike down.
What has a pivot point between a load and an input force?
The answer is: a lever.A lever is a simple machine that has a stick that pivots at a point called a Fulcrum.There are 3 types of Lever:First class lever: A first class lever is when a fulcrum is in the middle of the input force and the load. An example is a seesaw in the playground. When you press down the side of seesaw,(input force) the other side goes up. (load, output force) In the middle, there is a fixed point.Second class lever: A second class lever is where you have the load in the middle of the Fulcrum and the input force. An example would be a wheelbarrow. The basket in the middle is the load( also called the output force) the wheel at the end is the Fulcrum, and the handle that you press up and down is the input force.Third class lever: A third class lever is a lever that has a input force in between the Fulcrum and the Load. An example is a Hammer. The sharp part is the load(output force) the part you grab and swing is the input force, and the other end of the hammer is the Fulcrum.
Which fulcrum location required us to push down the lever the least to lift the load?
The fulcrum should be as far as possible from the effort to minimise the force needed. It should also be as close to the load as possible.
How are tongs a third class lever?
the fulcrum is where the parts of the two metals meet. Then, you push down in the middle of the tongs. (this is the input force). Then, the output force is the ends of the tongs pushing down or towards each other.
Which is the simple lever which helps to change the direction of a force?
A first degree lever, with the fulcrum between the force and the load, will change the direction of the force. Think of an adult on the ground pushing down on a see-saw to lift a child on the other end up into the air.
