Why the coefficient of friction cannot be zero?
The coefficient of friction is an empirical measurement and has to be measured experimentally, and cannot be found through calculations. Rougher surfaces tend to have higher effective values. Most dry materials in combination have friction coefficient values between 0.3 and 0.6. Values outside this range are rarer, but Teflon, for example, can have a coefficient as low as 0.04. Therefore, a value of zero would mean no friction at all, an ELUSIVE property even magnetic levitation vehicles have drag.
Can a coefficient of friction be equal to zero?
No , coefficient of friction can not be zero. if it is zero then there will be no frictional force between two bodies.And in our universe these types of object didnot exit.
What is the equation thast describes how air resistance affects terminal velocity?
down and up forces balance at terminal velocitymass * g = v^2 * drag coefficientif mass and terminal velocity are known , drag coefficient can be foundsay mass = 100 kg, g = 9.8 (m/s)/s, terminal velocity = 70 m/sso at terminal velocity:100*9.8=4900* drag coefficientthen:100*9.8/4900 = 0.2 (drag coefficient)if you reduce the drag coefficient, the terminal velocity will increase, until the forces balance
Can the coefficient of friction ever be zero?
No, the coefficient of friction cannot be zero because some level of resistance is always present when two surfaces come into contact with each other.
Which material has nearly zero temperature coefficient?
Invar is a material that has a nearly zero temperature coefficient, meaning its dimensions do not significantly change with fluctuations in temperature. This makes it valuable for applications where dimensional stability is critical, such as in precision instruments and scientific equipment.
What is the zero lift drag coefficient of Airbus A330-200?
coefficient of drag in 0 lift
What is zero lift coefficient of drag?
For no lift, The induced drag will be zero. However, there will still be drag due to viscous forces and pressure forces.
What is the zero lift drag coefficient of airbus A380?
0.032
What is the zero lift drag coefficient of Airbus a340?
The zero lift drag coefficient (C_D0) for the Airbus A340 is typically around 0.025 to 0.030. This value represents the drag experienced by the aircraft when it is not generating lift, primarily due to factors such as skin friction and form drag. Exact values can vary based on specific configurations and conditions, but this range is commonly referenced in aerodynamic studies for the A340.
What is the value of zero lift drag in Airbus a380?
17.4
A correlation coefficient of zero indicates?
A correlation coefficient of zero means that two things are not correlated to each other.
Is it possible for a coefficient of variation of a set of data to be zero Explain.?
Yes it is. If all the observations have the same non-zero value then the coefficient of variation will be zero.
If coefficient of skewness equals 0 then what would you say about the skewness of the distribution?
if coefficient of skewness is zero then distribution is symmetric or zero skewed.
What does a correlation coefficient of zero indicates?
A coefficient of zero means there is no correlation between two variables. A coefficient of -1 indicates strong negative correlation, while +1 suggests strong positive correlation.
