Q

Type 1 friction problem

Solve for P on a hortizontal surface.

A

In this problem the pulling force equals the friction force just at the point of moving.

Q

Type 2 Find the force at an angle on a hortizontal surface.

A

Here you need to find the angle of static friction (this then cancels out the Rn and Ff forces).

Once you have this add vectors 1,2,and 3 starting at weight.

Use the sine rule to solve for F.
