เส้นแนวแกนของรถไม่ได้ผ่านจุดสัมผัสพ

The axis of the vehicle through the front wheels touch the ground. However, the vertical distance l from the point of contact with the ground. As shown in Figure (2), which is an arm of the force of friction on the bicycle on the axial tilt to the left.f takes the floor, moments of force (f × l) acting on the front wheels. The moment of this force will cause the front wheel to the left, twisting it. So we can rely on the arm of the balance of the bike. Although we will release it.(1) it is not possible to move the hand truck to maintain balance. Necessary to tilt the balance has to be maintained.

Line alignment of the vehicle does not pass the point of touching the surface of the front wheel, but the vertical distances. L from touching the ground, as shown in figure (2), that is, the force of arms, the friction surfaces have the catalyst when the bike tilting to the left. F that the ground force's torque (f×l) made to the front wheels and torque of this force will cause the front wheel to twist it to the left to fit. Therefore we can rely on the force of arms, maintain the balance of the bike, even though we will be releasing. (1) it will not be able to move your hands to maintain balance. Need to tilt the back to maintain balance.

line scan through the access point of the car is not touch the floor of the front wheel, but it is a vertical distance L from the point touch the floor as shown in the figure (2), which is the force of his arm friction on the floor with a bicycle at an angle to the vertical axis on the leftF on the floor will cause โมเมนต์ of strength (F × L) against the wheels of this page, and โมเมนต์ will make the wheels fit the twist to the left, so we can rely on the arm of the balance of a bike even though we let it go.(1) it will not be able to move a car hands-to maintain the balance necessary to be tilted, to maintain the balance, it will be.
