How can the efficiency of an inclined plane be increased?
Efficiency is the ratio of power output to power input. It is not the ratio of forces or distances. You can move a load using less force by reducing the gradient of the plane. But what you gain in reduced force you lose in having to travel a greater distance to raise the load through the same height. There is, therefore, no net advantage. The only way to increase the efficiency is to reduce the friction. This can be done by lubricating the plane, or load (or both), or by placing rollers between the load and the plane - so that there is rolling friction rather than sliding friction.
What is the ratio for the volumes of two similar spheres given that the ratio of their radii is 27?
If the ratio is 2 : 7 then the volumes are in the ratio 8 : 343.
What is the ratio for the volumes of two similar spheres given that the ratio of their radii is 2 7?
It is 8 : 343.
What is the ratio for the volume of two similar spheres given that the ratio of their radii is 5 9?
3/4
What is the ratio for the volumes of two similar cylinders given that the ratio of their heights and radii is 3 7?
It is 27 : 343.
What is the ideal mechanical advantage of inclined plane?
The ideal mechanical advantage of an inclined plane is a ratio describing the length one has to travel to raise a load by a desired height. To obtain this ratio, divide the length of the plane's sloped face by the height of the inclined plane. IMA = Slope length / height
What is the mechanical advantage of an inclined plane that is vertical?
It is equal to the ratio of the load divided by the distance of the fulcrum.
What is the wind velocity in the back blast area in a jet runway?
Jet engine blast is a lot more than the plane move. A velocity of jet engine exhaust velocity is 3200 m/s for boing 747-400 top speed (velocity 212 m/s).Addition to thruster velocity principle:Velocity is associate with momentum of plane where the mass of air to move must be balance with its' velocity in compare to plane mass and velocity.Where the plane is massive in ratio to exhaust thruster mass. Thruster must be compensate with higher velocity in the ratio to plane mass.
What is the use of gangplank in the simple machine?
A gangplank is also known as an inclined plane it is a flat surface whose endpoints are at different heights. By moving an object up an inclined plane rather than completely vertical, the amount of force required is reduced, at the expense of increasing the distance the object must travel. The mechanical advantage of an inclined plane is the ratio of the length of the sloped surface to the height it spans; this may also be expressed as the cosecant of the angle between the plane and the horizontal. Note that due to the conservation of energy, the same amount of mechanical energy is required to lift a given object by a given distance, except for losses from friction, but the inclined plane allows the same work to be done with a smaller force exerted over a greater distance.
Can a simple inclined plane have a mechanical advantage less than one?
The mechanical advantage of an inclined plane is the ratio of its length to the height of its lift. At 45 degrees, this ratio is equal to one. Less than 45 degrees and it is greater than one, more than 45 degrees, and it it less than one. So the answer is yes.
What is velocity ratio?
it is the ratio of the velocity of the point of application of effort to the velocity of the load
What is the best definition of velocity?
The speed of something in a given direction.
Why is gear ratio also called velocity ratio?
The gear ratio of a train, also known as its speed ratio, is the ratio of the angular velocity of the input gear to the velocity of the output gear. The gear ratio is very important when it comes to physics.
Does friction affects velocity ratio?
No. The velocity ratio remains constant but the friction absorbs power.
How do you calculate velocity ratio in a pulley?
the circumference ratio
What is the relationship between ideal mechanical advantage and velocity ratio?
The ratio of Mechanical Advantage and Velocity Ratio is Efficiency. That is to say the ratio of M.A. and V.R. is constant.

principle used in increasing velocity ratio of diffrential and wheel
