Page 8-25. There it was: a clean free-body diagram with the friction vector down the plane (she’d put it up — wrong assumption), and the normal force correctly split into components. Step by step, Hibbeler’s method revealed her mistake: she’d used the wrong friction direction because she’d forgotten that impending motion up means friction acts down .

After class, Hendricks smiled. “You actually used the manual the right way, didn’t you?” Page 8-25
