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.

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.
