ANSWER:
Step 1 of 3
Part a
We are required to determine the angle for the crate to slide if the given coefficient of static friction is 0.415.
In the example 6-3, the coefficient of friction is 0.429 for the tilt angle of 23.20.
When the coefficient of friction is 0.415, the tilt angle would decrease too. So, the angle is less than 23.20.
