Homework Help: Physics

Posted by Alex on Saturday, March 8, 2008 at 6:34pm.

A semi- trailer truck (seen from back) of mass M is negotiating a right hand curve on a level highway, The constant speed of the truck is v and the radius of curvature of it's circular trajectory is R. The road exerts normal forces on the trucks tires F1, F2 and a horizontal static friction force on each tire f1, f2 directed toward the centre of the curve. The trucks centre of mass is a height H above the road and the distance between the tires is W.

Apply newtons second law(s) in the non- inertial frame moving with the truck to find the magnitudes of the normal forces on terms of M,g,v,R,W. Assume the truck can be treated as a lamina lying in the plane of the page.
