my sprocket is rigidly attached to rear axel ,is there any difference in torque at sprocket and tire?
will you please elaborate your question?Chestermiller said:What do you get if you apply an angular momentum balance to the wheel?
less bcz torque =force*radius and in this case sprocket radius is less than that of wheelsOldYat47 said:Or more basically, suppose you have some torque at the sprocket. Would you have to exert more or less rotating force at the tire to create that same torque at the sprocket? Remember that torque = force times radius.
The sprocket torque minus the tire torque is equal to the wheel moment of inertia times the angular acceleration of the wheel. If the bike is not accelerating, then the sprocket torque is equal to the wheel torque. (I assume that by sprocket torque, you are referring to the torque applied by the chain to the sprocket).Aashish sarode said:will you please elaborate your question?
If the car isn't accelerating, it sure is the same. The moments (torques) must balance. Just take the wheel and attached sprocket as a free body.OldYat47 said:Exactly. The farther you get from the center of rotation the less the torque. So the torque at the sprocket is not the same as the torque at the tire.
The torque is absolutely the same. The force, however, is not, since as you pointed out earlier, torque is force multiplied by radius.OldYat47 said:Exactly. The farther you get from the center of rotation the less the torque. So the torque at the sprocket is not the same as the torque at the tire.
power=torque*angular velocity , since pChestermiller said:The sprocket torque minus the tire torque is equal to the wheel not accelerating, then the sprocket torque is equal to the wheel torque.

hmm ,power remains constant i.e power =torque *angular velocity ,angular velocity for sprocket and wheel is same so torque nust be equal. Thank u all.cjl said:The torque is absolutely the same. The force, however, is not, since as you pointed out earlier, torque is force multiplied by radius.

Tire torque is the rotational force that a tire applies to the ground when a vehicle is in motion. Traction force is the grip or friction between the tire and the ground that allows the vehicle to move forward.
A sprocket attached to the rear axle increases tire torque and traction force by providing more power and leverage to the tires. This allows for better acceleration and grip on the road.
The weight of the vehicle, the type and condition of the tires, the road conditions, and the power and torque of the engine are all factors that can influence tire torque and traction force.
Tire pressure can greatly affect tire torque and traction force. Over-inflated tires can reduce traction by reducing the surface area of the tire in contact with the ground, while under-inflated tires can decrease tire torque and grip on the road.
Regular maintenance of tires, such as keeping them properly inflated and replacing worn tires, can improve tire torque and traction force. Additionally, using tires with a tread design and rubber compound specifically designed for improved grip can also enhance tire torque and traction force.
