How do you calculate the ideal mechanical advantage of a lever?
It's 1. IMA = Distance in / Distance out. A single pulley doesn't do anything toward mechanical advantage, it changes the direction of the force. Not always. A single-axeled pulley (the typical pulley) has an IMA of 1, having one axel. If there was a second axel, then the IMA would = 2, so on and so forth. The easy way to do it is IMA = # of axels.
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
How does the current flowing in a conductor depend on the number of mobile charge carriers per unit length on their average velocity on the charge per carrier?
the flowing in the conductor is related as given by the relation... I=Vena v=drift velocity of electron e=charge on electron n=concentration of electron in the current carrying conductor . a=area
How can you calculate water velocity from flow rate or diameter of pipe?
if u r talking about presuure drop then it can be easily calculate with the help of relation 4flv*v/2gd in that f is the friction factor which is different for vraious type of flow for that u have to search a good book of fluid mechanics, v is the velocity. length of pipe and d is diameter of pipe
Why velocity of current equal to velocity of light?
Because charge particles produces magnetic field which causes electromagnetic force that's why moving charges move with the velocity equal to the velocity of light.
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.
What are efficiencies?
efficiency is defined as the concept of mechanical advantage and velocity ratio.
How do you calculate effort the machine of velocity ratio 5 and efficiency 60 percent calculate the effort required to lift a load of 300N?
efficiency=mechanical advantage/velocity ratio mechanical advantage=load/effort use this formula, ans:100N
Describe the difference between mechanical advantage and velocity ratio. what does each type of calculation represent?
....................
Relation between linear velocity and angular velocity?
linear velocity= radius* angular velocity
Is velocity kinetic energy?
No. This is because velocity is not a mechanical energy.
Relation between angular velocity and linear velocity?
Both have mileage.
What is velocity-time relation?
Velocity is measured as distanced traveled over time
What is relation between linear velocity and angular velocity?
velosity in circular path angular
Is air travel energy requirements the same whether or not the plane is flying with or against the rotation of the earth?
That should be the same; what matters to the plane is the velocity in relation to the air, not in relation to some frame of reference outside the Earth.That should be the same; what matters to the plane is the velocity in relation to the air, not in relation to some frame of reference outside the Earth.That should be the same; what matters to the plane is the velocity in relation to the air, not in relation to some frame of reference outside the Earth.That should be the same; what matters to the plane is the velocity in relation to the air, not in relation to some frame of reference outside the Earth.
What do you mean by critical velocity by method of dimensions establish its relation?
Critical Velocity has the same dimensions as of velocity & terminal velocity. [L/T]
What the different between velocity and speed?
Speed is scalar quantity and velocity is a vector - velocity has both speed AND direction (You might say that velocity is speed with an attitude!)
