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.
Why does the mechanical advantage of an inclined plane can never be less than 1?
The mechanical advantage of an inclined plane is the ratio of the length of the inclined plane to the height it lifts a load. Since the length is always greater than the height (unless the inclined plane is vertical), the mechanical advantage is always at least 1.
What is the ideal mechanical advantage of inclined plane?
The ideal mechanical advantage of an inclined plane is the ratio of the length of the incline to the vertical rise. It is calculated by dividing the length of the ramp by the vertical height of the ramp.
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.
How does a decrease in height affect the actual echanical advantage of the inclined plane?
A decrease in height of the inclined plane will result in a lower mechanical advantage. Mechanical advantage is calculated as the ratio of the length of the inclined plane to the vertical height. Therefore, as the height decreases, this ratio decreases, leading to a lower mechanical advantage.
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 mechanical efficiency of a inclined plane?
The mechanical efficiency of an inclined plane is the ratio of the output force to the input force, taking into account friction and other factors that may reduce efficiency. It is calculated as the ratio of the ideal mechanical advantage to the actual mechanical advantage. A perfectly efficient inclined plane would have a mechanical efficiency of 100%, but in reality, efficiency will be less than 100% due to energy losses.
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 the best definition of velocity?
The speed of something in a given direction.
Why can't the mechanical advantage of an inclined plane can never be less than one?
The mechanical advantage of an inclined plane can never be less than one because it is defined as the ratio of the length of the incline to the vertical height it spans. Since inclines always extend over a longer distance along the slope than they do vertically, the ratio will always be equal to or greater than one.
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?
Friction can have an impact on velocity ratio by reducing the efficiency of a system. Friction can transfer energy into heat, causing a loss in velocity and making it more difficult to maintain a consistent velocity ratio. Reducing friction through lubrication or other means can help improve the velocity ratio.
What is velocity ratio?
Velocity ratio is the ratio of the distance moved by the effort to the distance moved by the load in a simple machine. It represents the trade-off between force and distance in a machine. A higher velocity ratio indicates that the machine can move the load a greater distance with a smaller input force.
