Degrees versus radians.emily081715 said:
i don't understand?haruspex said:
Did you plug the 19 degrees into the tan function of a calculator? It can probably be set to expect angles to be specified in degrees or radians, but you have to make sure you select the right one.emily081715 said:

Why the 9.8? g is not part of the coefficient.emily081715 said:
well actually i know its incorrectemily081715 said:
so just tan (19)emily081715 said:
Yes.emily081715 said:
The minimum coefficient of static friction is a measure of the minimum amount of force required to keep an object at rest on a surface. It is a dimensionless number that represents the ratio of the maximum frictional force to the normal force between the object and the surface.
The minimum coefficient of static friction is determined through experimentation and measurement. It involves gradually increasing the applied force on an object until it begins to move. The minimum coefficient of static friction is then calculated by dividing the magnitude of the maximum frictional force by the normal force.
The minimum coefficient of static friction is influenced by several factors, including the nature of the surfaces in contact, the weight and geometry of the object, and the roughness of the surfaces. It is also affected by external factors such as temperature and humidity.
The minimum coefficient of static friction is an important concept in physics and engineering because it helps determine the stability and safety of objects on a surface. It is also used in designing structures and machines to ensure that they can withstand the necessary forces without slipping.
The minimum coefficient of static friction is typically higher than the coefficient of kinetic friction. This is because it takes more force to overcome the static friction and initiate motion than it does to maintain motion. The coefficient of kinetic friction is also affected by factors such as the speed of the object and the presence of lubricants.
