Homework Statement
If you have an object say in a vertical pipe, which only has a gravitational force acting on it would the reaction forces only be friction forces?
If this is the case how would you calculate the forces? would you calculate the friction force using the friction coefficient or just take Fy as friction?
Homework Equations
Friction F=Friction coefficient * F(n)
Fy= F*sin(theta)
The Attempt at a Solution
I would say that all forces acting against gravity would be friction forces, also assuming the object is at equilibrium then static friction would act in an upwards direction.
