## Coefficient of Friction at an Angle Formula

The following formula is used to calculate the Coefficient of Friction at an Angle.

**Ca = C * SIN(a)**

- Where Ca is the Coefficient of Friction at an Angle
- C is the standard coefficient of friction
- a is the angle of the friction

## How to Calculate Coefficient of Friction at n Angle?

The following two example problems outline how to calculate the Coefficient of Friction at n Angle.

**Example Problem #1:**

- First, determine the standard coefficient of friction. In this example, the standard coefficient of friction is given as 100.
- Next, determine the angle of the friction. For this problem, the angle of the friction is given as 40.
- Finally, calculate the Coefficient of Friction at n Angle using the equation above:

Ca = C * SIN(a)

Inserting the values from above and solving the equation:

Ca = 100 * sin(40deg) = 64.278

**Example Problem #2: **

Using the same process as above, first define the variables required by the formula. In this case, these values are:

standard coefficient of friction = 200

angle of the friction = 35

Entering these values yields:

Ca = 200 * SIN(35deg) = 114.71
