Unformatted text preview: HW 11: Do the modified version of Problem 4.89 as described below: PROBLEM 4.89 A slender rod of length L and weight Wis attached to a collar
at A and is ﬁtted with a small wheel at B. Knowing that the
wheel rolls freely along a cylindrical surface of radius R, and
neglecting friction, derive an equation in 9, L, and R that must
be satisﬁed when the rod is in equilibrium. PROBLEM 4.89 Modified: Let W = 100 N and 6 = 55°.
Find the force at A, the components of the force at B
(I?)X and By). For length AB use the symbol L. Does it drop out? Find the direction (angle) of the resultant force B and show that it points toward C. Partial answers: FA=71.41 N, Bx=71.41 N, By=100 N. Free-Body Diagram ‘ ...
