Connecting rods.—What are the two principal kinds of connecting rods? What is meant by the angularity of a connecting rod? [II. 375].
Oiling guide bars.—Which guide-bar is the most difficult to oil, the top or the bottom one? [II. 375].
Effect of angularity.—What effect does the angularity of the connecting rod have on the piston motion? Is this effect increased or diminished by shortening the connecting rod? [II. 375].
Crank at full power.—When the crank is at its point of full power, is the piston in the middle of the cylinder? Is it nearer to the crank-end or the head-end of the cylinder? [II. 375].
Piston motion irregular.—What causes the piston to have irregular motion? [II. 375].
Live steam period.—What constitutes the live steam period of a position? [II. 376].
Cut-off.—What is the point of cut-off? [II. 375].—What is a separate cut-off valve, and what event does it control in the supply of the steam to the cylinder? How is the point of cut-off varied when a cut-off valve is used? [II. 378].
Working expansively.—What causes the steam to be worked expansively in an engine cylinder? [II. 402].
Follower.—- What is a piston follower? [II. 374].
Valve lead.—What is the lead of valve? [II. 376].
