how to work out "frictional torque" A Mass of 0.5 kg is suspended from a flywheel. If the mass is released from rest and falls a distance of 0.5 m in 1.5 s, calculate the tension on the rope the frictional torque, resisting motion Mass of flywheel = 3 kg radius of wheel = 300mm radius of gyration = 121mm so this is what i have worked out so far
Welcome to the PF. The basic equation for frictional force is F = mu * N, where mu is the friction coefficient, and N is the normal force. For the case of the wheel on the axle, you will need to figure out the distribution of the normal force as a function of the angle. Max force on top and tapering off as you get to the sides of the axle.
The average frictional force is calculated by multiplying the coefficient of friction, which is a measure of the roughness or smoothness of the surfaces, by the normal force, which is the force exerted on an object by a surface perpendicular to that object.
The frictional force equation is a mathematical formula that represents the force of friction between two surfaces in contact. It is typically written as Ff = μN, where Ff is the frictional force, μ is the coefficient of friction, and N is the normal force.
The frictional force equation is a mathematical representation of the force that opposes motion between two surfaces in contact. It is given by the formula F = μN, where F is the frictional force, μ is the coefficient of friction, and N is the normal force.
A differential equation of frictional force is derived using Newton's second law of motion, which states that the force on an object is equal to its mass multiplied by its acceleration. By considering the forces acting on an object in contact with a surface, and using the definition of frictional force, a differential equation can be formed.
The coefficient of kinetic friction is 0.266. The work done by the force is 351 J, the work done by the normal force is 0 J, and the work done by the gravitational force is 0 J. The energy lost due to friction is 162 J, and the total change in the block's kinetic energy is -189 J. The normal force is 124 N and the frictional force is 33 N.
FAQ: Finding Frictional force from the magnetic equation Fb=BIL 1. What is the magnetic equation Fb=BIL? The magnetic equation Fb=BIL is a mathematical expression used to calculate the force (Fb) experienced by a charged particle moving through a magnetic field (B) with a velocity (v) and an electric current (I).
The conversation also includes attempts at a solution using equations such as force equals mass times acceleration and friction equals the coefficient of friction times the normal force. However, it is ultimately determined that conservation of energy and the equation for kinetic energy can be used to solve the problem.
The frictional force equation, also known as the Coulomb's law of friction, is a mathematical formula that describes the force of friction between two surfaces in contact. It is given by F = μN, where F is the frictional force, μ is the coefficient of friction, and N is the normal force between the two surfaces.
