the in-clined plane; given the inclination of the beam to the plane,required that of the plane to the horizon. Let AgB be thebeam movable aboutA, w= weight ofbeam acting at g, B-Pj the point of contactwith the spherewhose center is C,m>== weight of thesphere. The sphere is in equilibrium, from… … EXAMPLES ON THE PRECET/NG CHAPTERS. 71 instead of either of the two latter, the radius of the sphere maybe given. The angle DAE = 0, the inclination of the planewhen in equilibrium, is required. » For the condition of equilibrium of the beam, take the mo-ments about A. P.AB=w.Ag. cos. (a+6). Hence…
