A disk that weighs 20 lb sits on the floor at point B with a coefficient of static of 0.2. A rope is wrapped around the disk and connected to block C, which rests on the floor with a coefficient of static friction of 0.3 at point D. Determine the smallest force, P, which can be applied tangential to the desk that will cause motion to expand (o.r. just on the verge of moving).

Respuesta :

The smallest force, P, which can be applied tangentially to the desk that will cause motion to expand is reactive force. hence, R = 39.2 N

given

lowest coefficient of static friction is 0.2

mass = 20lb

we know that reaction is also a type of reactive force.

[tex]R = \mu \times m \times g[/tex]

[tex]R = 0.2 \times 20 \times 9.8\\R = 39.2 N[/tex]

What is force?

  • A force in physics is an effect that has the power to alter an object's motion. A force can cause an object with mass to accelerate when it changes its velocity, for as when it moves away from rest.
  • An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction. It is calculated using the newton SI unit (N). Force is denoted by the letter F. (formerly P).
  • The net force acting on an object is equal to the rate at which its momentum varies over time, according to Newton's second law in its original formulation.
