For the Model 7520-DR32TT Deep Reach Carriage calculate the roller forces and chain tension when (a) the payload is retracted, and (b) the payload is extended. For each case first include a complete free body diagram. These have been started for you, below. Be sure to include a discussion of your results. Note 1: Rollers will only support loading in the X-direction while the chain supports loading in the Y-direction. Note 2: There are two sets of rollers and two chains supporting the load; the other pair is on the opposite 2D view of this 3D body. Additional information on the location of the center of mass and applied forces is given below: a) Reach Retracted b) Reach Extended PAYLOAD PAYLOAD R1 R1 CARRIAGE CARRIAGE R2 R2 Y-CG (in.) 14.6 20.0 Mass X-CG Mass X-CG Component Y-CG (Ibm.) 1,420 3,200 (in.) 36.8 84.3 Component (Ibm.) 1,420 3,200 (in.) 9.6 41.3 (in.) 12.7 CARRIAGE CARRIAGE PAYLOAD PAYLOAD 20.0 Magnitude (Ibf.)
