Check the choice of pulleys according to the following instructions:

- Find out the maximum rpm for the engine (Max).

- Find out the engine's rpm when traveling at maximum, continuous

velocity (Max

cont

- Divide the diameter of the large pulley (D

) with the diameter of the

small pulley (dsp). Multiply the result with the maximum rpm for the

engine (Max

rpm

). This result must not exceed 18 000 rpm. If it is larger a

smaller pulley should be chosen for the crankshaft.

If the results of the above computations are not acceptable, pulleys with

different diameters must be selected.
