With inclining the velocity of vehicle the cost will become low dominantly when the velocity attains 19Km/h and 26Km/h in future. With increasing time the movement, the velocity and acceleration of vehicle will become sinusoidal wave. When the crank length increases from 70mm to 100mm under linkage length L=180mm the maximum movement, velocity and acceleration will increase and the minimum ones will increase. The phase angle will decline with inclining speed with sinusoidal wave but the size of them maintains unchanged respectively. So it is chosen of the short crank and long linkage so as to maintain maximum force. To be rapid work the speed is needed highly.
