2 (d) Given the weights ( w 1 and w 2 ), determine the magnitudes of as many of the forces in your FBDs as possible. What can you say about the magnitudes of the other forces? 2. A ball of weight w rests in a wedge formed by two rigid, flat frictionless walls. ( Frictionless means the contact forces are perpendicular to the surface—i.e. there is

Unformatted text preview: a normal force but no frictional force.) (a) Draw a free-body diagram showing all the forces acting on the ball. (b) In terms of the angle θ and the ball's weight w , find the magnitudes of the contact forces acting on the ball due to each of the two walls. θ...
