Torque is increased on the larger, driven gear. The increase can be calculated as the ratio of the radii of the two gears. For example, if the small gear has a radius of 2 cm and the larger gear has a radius of 10 cm, the torque ratio is 10/2 (ten to two), or 5/1 (five to one). So the driven gear is producing 5 times the torque of the driving gear. The speed ratio is the reverse; the driven gear is rotating at 1/5 the speed of the driving gear.
Large drive pulley, small driven pulley = faster rotation but less torque. Small drive pulley, large driven pulley = slower rotation but more torque.
The engine rotates the principle drive at a constant velocity - this is connected to the final drive by way of a thick rubber belt which runs around between the principle drive's fixed diameter wheel and the final drive's variable diameter wheel. Imagine two cones placed together point to point. By moving these cones apart as the speed increases the belt drives a smaller and smaller diameter of the cones tips - the effect being very similar to a derailleur gear on a racing bicycle - large front / large rear = low gear, large front / small rear = high gear.
how do you measure diameter
The torque produced by the cars engine will be both static and dynamic, depending on where it is measured.If the torque is measured in the crankshaft, there will be large dynamic torque fluctuations as each cylinder fires and its piston rotates the crankshaft.If the torque is measured in the drive shaft it will be nearly static because the rotational inertia of the flywheel and transmission will dampen the dynamic torque produced by the engine.So the torque which fluctuates based upon the operating condition & other amplification factors, is called dynamic torque.Saurabh Solanki
They compensate for the smaller rear tires. The rear tires have to be small, in order to facilitate turning. The larger tires are used to drive the vehicle, so they need to have a large cross section to distribute weight evenly enough in order to prevent the vehicle from sinking into the ground. The large diameter of the tires also serves two functions - it helps keep the cab elevated above the radius of the head, and also keeps the vehicle geared low enough to deliver ample drive torque.

The diameter is twice as large as the radius.
The largest diameter airways are the mainstem bronchi. Smaller-diameter airways are the bronchioles.
A large force can produce a small or zero torque if the force is applied at a point where the lever arm (distance from the point of rotation to the line of action of the force) is very small or zero. Torque is calculated as force multiplied by lever arm, so a small lever arm can result in a small or zero torque even with a large force.
3,800 miles in diameter.
The small planets are the ones smaller than 8000 miles in diameter. The large planets are the large ones larger than 30,000 miles in diameter.
Torque is the product of (force) x (distance from the center of rotation).So with a distance from the center that's large enough or small enough,any force can produce as much or as little torque as you want.
