Why is a block and tackle useful?
A block and tackle magnifies the pulling force applied to rope. This is useful for moving heavy objects, lifting heavy objects, etc. A good Example is all the old sailing ships like in The movies "Pirates of the Caribbean" used block and tackle to move and trim the sails. This is still in use by window washers on skyscrapers to exercise machines.
How pneumatic and hydraulics systems multiply force?
a hydraulic device multiplies a force by applying the force to a small surface area. The increase in pressure is then transmitted to another part of a confined fluid, which pushes on a larger surface area. /\ | |__ this is pascals principle not the right answer..
What is stress force?
Well, darling, stress force is simply the force applied to an object per unit area. It's like giving someone a big ol' bear hug - the pressure you exert on them is the stress force. So, next time someone's stressing you out, just remember it's all about force and pressure, honey.
What is bearing stiffness?
All bearings and bushings have a basic stiffness. When you apply load on the shaft the shaft will move, and so the stiffnes can be calculated from the ratio of the applied force to the absolute value of movement.
How does air brake use pneumatic power?
An air brake uses a diaphragm connected to an operating rod to work the brake. Behind the diaphragm there is a spring which applies the breaking force at all times. To release the break either pressure is applied to the other side of the diaphragm or a vacuum is applied to the spring side. Because the diaphragm has a large surface area just a few p.s.i. can produce a large force. E.g. A 8 inch diameter unit would produce over 700 lbs thrust at 14psi this force is often further amplified by the leverage of the linkage. This arrangement makes the brake fail to the safe "on" state.
How are the input and output forces of the parts of a compound machine related?
In a compound machine, the output force of one part becomes the input force for the next part. This allows the overall machine to multiply the force applied to it by using a series of simple machines working together. The output force of the compound machine is the product of all the individual input forces and mechanical advantages of each part.
How many times a machine multiplies force?
A machine can multiply force multiple times, depending on the design and components involved in its operation. Systems such as pulleys, levers, and gear mechanisms are all examples of how machines can multiply force to achieve a desired output. Each component within the machine contributes to the overall force multiplication.
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.
A machine is used to multiply?
A machine used to multiply is typically referred to as a multiplier or a multiplication machine. It is designed to perform the mathematical operation of multiplication, which involves repeatedly adding one number to itself a certain number of times to achieve the product. These machines can vary in complexity and can be mechanical, electronic, or digital in nature.
How do you calculate the mechanical advantage of any machine?
distance over which the force is applied ________________________________ Distance over which the load was moved or MA= Effort Force _________ Load force OR MA= Length of Load arm ____________________X Weight/mass Length of Effort arm
Which simple machine multiply the distance?
A lever is a simple machine that can multiply the distance you apply force over. By adjusting the placement of the fulcrum, you can increase the distance the load moves relative to the distance you push or pull on it.
Which is true of all simple machines?
All simple machines change the direction or magnitude of a force to make work easier. They operate on a basic mechanical principle and do not have moving parts. Simple machines can be combined to create more complex machines.
What condition does an object on which a constant force is applied have a zero acceleration?
An equal and opposite force is also applied to the object, so that the vector sum of all the forces on it is zero.
What can happen to objects when force is applied on them?
If it is applied equally to all points, then the effect is to accelerate the body according to F = M * a. If it's not homogenous, then it may also cause a rotation.
When a force is applied to a confined fluid it?
When a force is applied to a confined fluid, the pressure within the fluid increases. This increase in pressure is transmitted equally in all directions, according to Pascal's principle. As a result, the fluid transmits the force to all surfaces in contact with it.
what are all the simple machine in a fridge?
Lever: A bar that turns around a fulcrum (pivot point) used to lift an object when a force is applied on the other side. Incline Plane: A sloped surface used to raise an object. Pulley: Used to change the direction of force and or multiply it.
An object will accelerate in the direction of the?
An object accelerates in the direction of the net applied force, which is the vector sum of all applied forces.
