Is angle of incidence always equal to angle of reflection?
Yes. Although it may not seem like it when the surface is curved, the angles are taken in respect to the "tangent" (derivative) to the curve.
What is the relationship between the angle of incidence and the angle of of refraction known as?
The COEFFICIENT of Refraction.
How do you find the vector components only given the magnitude and angle?
One component = (magnitude) times (cosine of the angle).Other component = (magnitude) times (sine of the angle).In order to decide which is which, we have to know the angle with respect to what.
What is the measure of the angle of rotation with respect to two lines that intersect to form a 25 degree angle?
50. It is always two times the rotation.
How do you find the angle of reflection off of a mirror?
The angle of reflection (θr) off a planar surface (eg. mirror) is equal to the angle of incidence (θi) on that surface. They are measured with respect to the normal, which is an imaginary line drawn perpendicular to the surface. Or, in simpler terms, the angle of reflection is the same as the angle of incidence.
What are the Trim conditions in aircraft?
An aircraft is at trim when it is flying under steady-state conditions (nothing is changing and the airplane is just zipping along).More specifically, trim conditions are when Clbeta (partial derivative of the roll moment coefficient with respect to beta [sideslip angle]), Cnbeta (partial derivative of the yaw moment coefficient with respect to beta [sideslip angle]) and Cmbeta (partial derivative of the pitch moment coefficient with respect to alpha [angle of attack]) are all equal to zero.
Is angle of incidence always equal to angle of reflection?
Yes. Although it may not seem like it when the surface is curved, the angles are taken in respect to the "tangent" (derivative) to the curve.
What is the relationship between the angle of incidence and the angle of of refraction known as?
The COEFFICIENT of Refraction.
how to draw graph Experiment to find coefficient of static friction?
To determine the coefficient of static friction, you can conduct an experiment by gradually increasing the angle of an inclined plane until an object on the plane just begins to move. You can measure the angle at which this occurs and use it to calculate the coefficient of static friction using the formula: coefficient of static friction = tan(angle).
How can you find the coefficient of friction force only given mass and theta?
The coefficient of friction is the tangent of the angle theta where the angle is measured from horizontal when the mass first starts to slip
What is the relationship between angle of friction and co-efficient of friction?
The angle of friction is the angle at which an object on a surface is on the verge of sliding. The coefficient of friction is a measure of the resistance to sliding between two surfaces. The tangent of the angle of friction is equal to the coefficient of friction between the surfaces.
How can an adjustable inclined plane be used to measure the coefficient of static friction and coefficient of static friction with a mass of 5.0?
To measure the coefficient of static friction, gradually increase the angle of the inclined plane until the object placed on it just starts to slide. Measure the angle at which this occurs and use trigonometry to calculate the coefficient of static friction. To find the coefficient of static friction with a mass of 5.0, repeat the same process with an object of that specific mass and calculate the coefficient using the same method.
What is the angle of friction?
The angle of friction is the angle at which a body will start sliding on a surface. It is equal to the arctangent of the coefficient of static friction between the two surfaces in contact.
Can an object move backward on an inclined plane?
Yes, if the incline angle becomes great enough. > As the angle increases, the force on the object down the incline increases but the effective weight on the slope surface decreases. > When the object breaks away the angle of incline can be used to calculate the coefficient of friction between the two surfaces. > coefficient of friction = sine ( incline angle ) / cosine ( incline angle )
How can an adjustable inclined plane be used to measure the coefficient of static friction and coefficient of kinetic friction?
An adjustable inclined plane can be used to measure the coefficient of static friction by gradually increasing the angle of the incline until the object just begins to slide. The coefficient of static friction can be calculated using trigonometry. The coefficient of kinetic friction can be measured by setting the incline at a known angle and measuring the acceleration of the object as it slides down.
What is the internal coefficient of friction for fertilizer?
It is the Emptying Angle of Repose that is greater than the Filling Angle of Repose. It is always the greater of the two Angles of Repose.
What is the maximum lift coefficient of NACA 2412?
Roughly 1.2 at an angle of 14 degrees (depends on Reynolds and mach numbers). Going over this angle will stall the profile.
