An inverted slider-crank linkage is being employed as a bicycle pump, as shown in Figure 7.144. The air inside the cylinder is at atmospheric pressure when the crank angle is at 90°, and reaches its maximum when the crank angle is at 10° from horizontal. The links have the following inertial properties:

m₂
= 0.1 kg                          I₂
= 0.0005 kg m²

m₃
= 0.250 kg                     I₃
=0.0004 kg m²

m₄
= 0.15 kg                        I₄
=0.0005 kg m²

Figure 7.144

The diameter of the piston is 50mm and it takes 1 second for one stroke of the pump. Assume that the center of mass of each link is at its centroid. Use MATLAB to plot the air pressure inside the cylinder and the x and y components of the user force at point Q for one stroke of the pump.
