Oh, my fault. I'm taking torque and around the point where the front wheel meet the ground. I'm then equating mah (the total force on the body times the length h between mass centre and A) with the torque on A.
ahh, thanks!
So how do I continue?
I've got the weight, and the normal and the friction force at the front wheel.
mag=F-mgsinβ
Ma=mah=mghsinβ-mgbcosβ
N=mgcosβ ??
Homework Statement
The bicyclist applies brakes as he descends a track making an angle β with a horizontal direction. The front wheel of the bike locks and starts to slip along the incline. Find the magnitude of the decleration a that would cause a dangerous condition of tipping about the...
