Which of the following statement is correct for a compound steam engine?

A The forces in the working parts are increased as the forces are distributed over more parts
B The cost of the engine, for the same power and economy, is more than that of a simple steam engine
C The temperature range per cylinder is increased, with corresponding increase in condensation
D The ratio of expansion is reduced, thus reducing the length of stroke

Correct Answer: The ratio of expansion is reduced, thus reducing the length of stroke

When the ratio of expansion is reduced, the length of stroke is reduced in a compound steam engine.
