Question:

Three blocks are connected by a weightless cord and rest on an inclined plane (Figure). Employing a procedure similar to the one used in the analysis of the falling parachutists in Example 9.11 yields the following set of simultaneous equations (free-body) diagrams are shown in Figure:

100? = T? ? ? ? ??= 519.72

?50? ? T + R? ?= 216.55

?25? ? R??= 108.27

Solve for acceleration ? and the tensions T and R in the two ropes.
