← HistoryWhich mechanical consequence occurred when early steam engines lacked sufficient structural support around the cylinder?
A)Cylinder warping and piston seizure✓
B)Increased coal consumption from heat loss
C)Pressure release from safety valve failure
D)Boiler explosions from metal fatigue
💡 Explanation
When early steam engines lacked support, cylinder deformation occurs because uneven thermal expansion caused warping exceeding material yield strength, leading to piston binding. Therefore cylinder warping results, rather than other failures which require exceeding pressure limits or thermal efficiency issues.
