In the preceding essay I discussed the stability of a three-wheeled truck at rest as well as in moton, on a hoizontal plane. Here I wish to discuss the effects of wheel-base, tread, centre of gravity, speed, turning radius and angle of inclination, on its stability, when it is running on an inclination. By this essay every disigners will be able to calculate the stability immediately except other trifles such as tire cushion and handle inclination.
