Q7: Two uniform rods AB and BC, each of mass m and length 2L, hang vertically under the influence of gravity from a fixed pivot A, as shown. They are freely hinges at A and B, so that they can swing in a vertical plane. A horizontal impalse P. acting in this plane, is delivered to tbe free end at C. let th and denote the horixetal component of the velocities of the e tres of the rods AB and BC respectively and let their corresponding angalar velocities be and (a) Express and win terms of v and (b) Find an expression for the impalsive reaction at A () Find the velocities and e (d) At what distance d from the free end C shoukd the horiaontal impulse P be applied, so that Note that the mass monent of inertia of a slender rod of length 2L and mass m about its centroidal axis isL 24 B. 21
