Mechanics - Friction | Olly Britton

Flashcards

What is the formula for the maximum friction?

\[F _ \text{max} = \mu R\]

What is $\mu$ when talking about friction?

The coefficient of friction.

What is $\mu$ if a surface is described as “smooth”?

\[0\]

If a block is being pushed with a $10\text{N}$ force but there is a $20\text{N}$ max friction, what will happen?

The block will not move.

What is the situation called when a block is being pushed with a $20\text{N}$ force but there is a $20\text{N}$ max friction?

A limiting equilibrium, the block will not move.

If a block is being pushed with a $30\text{N}$ force but there is a $20\text{N}$ max friction, what will happen?

The block will move with a $10\text{N}$ force.
