🔍 Key Concepts

• Look at how the power element is arranged in Figure A – do you see pistons, blades, or vanes? • Compare an axial piston design (pistons in line with the shaft) versus a radial piston design (pistons arranged around a center). • Think about how a turbine or sliding vane air motor would look in section – what shapes would you expect to see?

💭 Think About

• In Figure A, are there multiple small components moving in and out along the same axis as the shaft, or are there parts clearly arranged like spokes around a hub? • Do you see anything that looks like a turbine wheel with curved blades, or a rotor with long rectangular slots for vanes inside an eccentric housing? • Which options are specifically air motors, and which are hydraulic motors, and what kind of starting system is commonly used for tug generator engines?

✅ Before You Answer

• Identify whether the moving elements in Figure A are aligned parallel to the output shaft or arranged around it. • Check if there is any sign of turbine blades or sliding vanes; if not, those options are less likely. • Ask yourself whether this starter appears to use reciprocating pistons (pointing you to one group of answers) or rotating air devices (pointing you to the other group).
