Chapter 9, Problem 51(choose chapter or problem)
A block weighing 12 lb rests on an inclined plane, as indicated in Figure A. Determine the components of the weight perpendicular to and parallel to the plane. Round your answers to two decimal places. Hint: In Figure B the component of the weight perpendicular to the plane is the component parallel to the plane is Why does angle QOR equal 35? (Observing that angle POR is a right angle, that line segment PO is parallel to AC, and that OQ is perpendicular to AB may be helpful.)
