Try these first

1. 1.

   What principle does a double acting steam hammer operate on?

   Hint

   Think about how air pressure affects movement.

2. 2.

   What is the average blow rate for a double acting steam hammer?

   Hint

   Recall the range mentioned in the description.

3. 3.

   What percentage of blow energy is derived from steam or air in the double acting hammer?

   • 70%
   • 90%
   • 100%

   Hint

   Consider the efficiency of steam in generating power.

4. 4.

   True or False: Diesel hammers require external compressors for operation.

   • True
   • False

   Hint

   Think about the design and integration of diesel hammers.

5. 5.
