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 function of coefficient of static friction?
This coefficient of static friction is needed to find the frictional force between a body and a surface on which body has to move. If u (mu) is the coefficient of friction then uR gives the frictional force between moving body and surface. There is no unit for coefficient of friction. Here R is reaction which equals to the weight of the body
A solid homogenous sphere rolls without slipping down a plane that makes an angle of 30 degree with the horizontal find the linear acceleration of the sphere and the minimum coefficient of friction?
There is no minimum value for the coefficient of friction. And the linear acceleration will depend on its unknown value.
What is the coefficient of friction of stainless steel sheet astm a240 type 304?
You need to know both material involved in the friction to find the coefficient
How to find Force of friction around circle?
T1/T2=e^(mu*theta)where T1/2 are the tensions in the circlemu is the coefficient of frictiontheta is the angle of the circle in contact with the rope.
Can you give me an experiment to calculate the coefficient of static and dynamic friction?
Get a block of known mass, a protractor and a board; the materials should be chosen as those for which you want to find the friction coefficients. Place the block on the board and gradually increase the angle of the board while keeping track of the angle the board makes with horizontal. The angle at which the block slips is crucial. The friction force opposes the movement of the block based on the normal force applied on the block by the board. As you increase the angle, the normal force decreases. F = uN where F is the friction force, N is the normal force and u is the coefficient of friction, in this case, static. Using the angle at which the block slips, calculate N; N = m sin(@) where m is the mass of the block, and @ is the measured angle. Now F must be equal to the force of gravity pulling on the block parallel to the board, otherwise the block would slip (and it does precisely at the measured angle) so; F = m cos(@) where m is the mass of the block and @ is the measured angle. Now that F and N are known, use the aforementioned relationship to calculate u. This value should be non-negative and has no units. As for dynamic friction; let the block slide from the top of the board when it is at a high angle and gradually decrease the angle until the block comes to a stop on the board due to friction. This should be done in trials of larger degrees until a working angle is found, then more precise trials can commence. When such an angle is found that any higher angle allows the block to keep going all the way to the bottom, the same calculations as above must be repeated to find the coefficient of dynamic friction.
How do you find the coefficient of static friction?
Use the formula: FsMAX=μsFN if you want to do it experimentally, get the two different surfaces, and angle one until the object on top starts moving. take the tangent of the angle that starts the objects sliding past one another, and that is your coefficient of static friction.
What are the two factors that affect the amount of friction between two objects?
Friction is determined by the formula Friction = μFN or alternatively Friction = μFGcos(θ). Therefore the two factors are: (1) the coefficient of friction that depends on the two particular materials (μ) and (2) the normal force operating on the object that is pressing against a larger surface (FN / μFGcos(θ)). Normal force itself has three components upon which it depends: (a) the mass of the object upon which the force acts, (b) the gravity of the body on which the events take place (usually Earth), and (c) the angle of the surface as it deviates from a straight horizontal surface.
How do you find the force of contact between two blocks?
It depends how they are in contact. If one is simply resting on top of the other you need to take into account, the friction coefficient which can be calculated from the Reynolds number of the particular material; and the mass of the object as the heaver it is the more friction will come into play.
How do you find the minimum coefficient of static friction for a mass on an incline of 32 degrees?
The equation for friction is F=uN. F (friction), u (coefficient of friction), and N (normal). So you first need to solve for the normal by using Newton's second law. Also solve for the x component of the gravity force. Since it is static friction, you know it should be at rest, so that x component force should be the same as the force of friction. Knowing that and the normal, plug it into the equation and solve for u.
How can you measure the sliding friction?
In physics a number known as the 'coefficient of friction' is used to calculate the frictional force between any two surfaces. Ff=µFn, Meaning that the frictional force (Ff) is equal to the coefficient of friction (µ) multiplied by the normal force (Fn). If one wishes to calculate the coefficient of friction for two objects, you can pull an object of whatever material you wish along a floor of whatever material you wish. As long as the object remains at a constant speed, the force which you use to pull the object (which can be measured by a force meter) is equal to the frictional force. Once you find the normal force (to find the normal multiply the mass of the object by the acceleration due to gravity on your part of the world, Fn= mg) you simply divide the frictional force by the normal force and you have the coefficient of friction. or just ask your teacher lol
How do you find kinetic friction without the coefficient?
by experiment. attach a pulley to the edge of a table. attach a known weight to a string through the pulley to another known weight on the table-top. put the particular surface who's coefficient of friction you wish to measure between the table top and the second known weight set on the table top. allow the first know weight to fall. measure its rate of descent. compare its rate of descent with that of the free fall acceleration of gravity for your particular latitude. you now have all the data you need to figure out the coefficient of kinetic friction. can you do that yourself or do you need to know more?
