Figure 4 shows a 27-kg concrete block that has been positioned on a 20° incline. As shown in the figure, there is space restriction so a rope is used to move the wedge to position the concrete block. At impending motion: a) Draw the free body diagram of the concrete block with an appropriate coordinate system. b) Calculate the direction and magnitude of the contact force from the wedge to the concrete block.
