3. As shown in the Figure 12, for the variable speed cylinder, a and b are the oil inlet andc is the oil return port. It is already known that D3D200 mm, d1=160 mm and d=40mm. The flow rate of the hydraulic pump is q=60L/ min. Calculation: the velocity of the piston when the pump only supplies oil to port a and the velocity of the piston when it supplies oil to port a and b at the same
