Rotational inertia plays a similar role in rotational mechanics to mass in linear mechanics. 11. If radius decreases then angular velocity or speed increases OK! Now if something was travelling at a speed v1 before decrease in radius and v2 after decrease in radius then we know v2>v1 right if no force was applied to it. 5 × 0. Torque is a kind of twisting force. In vector form, torque is the cross product of the radius vector (from the axis of rotation to the point of application of force) and the force vector. Again, shoving toward the axis of rotation isn't going to cause any rotation either and, once again, the mathematics supports this intuition. 21 ). Calculate the wheel torque and force (traction) for a vehicle with the following parameters: engine torque, T e = 150 Nm; wheel radius, r w = 0. Force is the applied force perpendicular to the radius and is typically measured A centripetal force (from Latin centrum, "center" and petere, "to seek" [1]) is a force that makes a body follow a curved path. In summary, the torque is defined as FxR, where F is the force applied and R is the distance from the axis of rotation. Torque is the cross product between the distance vector, a vector from the point of pivot (A) to the point where the force is applied, and the force vector. 4 is assumed for fully conditioned pads of standard material).
