4. Mensuration. Solids, Approximate Determinations, Metric
Measures, Plane Figures.
5. Squared Paper. Determination of maximum and minimum values;
the solution of equations; the roots of equations may be obtained
by the use of squared paper; rates of increase; speed of a body;
determination of laws which exist between observed quantities, especially linear laws. Corrections for errors of observation,
when the plotted quantities are the results of experiment.
MACHINE DRAWING.
A lecture of half-an-hour's duration will be given each evening upon the forms and construction of various machine and engine parts. The students will make dimensioned sketches of the details
illustrated on the black board, or from the actual objects shown during the lectures, and the remaining time will be devoted to making full size or scale drawings from the sketches. The examples will include:- Bolts, nuts and set screws; pins, keys and cotters; shafting, couplings and clutches; rivets and rivetted joints, pedestals and foot steps; toothed wheel gearing; pulleys and wheel cones; cranks and eccentrics; connecting rods, cross beads, pistons, stuffing boxes and glands; pipe joints, various valves and cocks, engine cylinder and slide valves.
APPLIED MECHANICS.
The subjects mentioned in the elementary course will be treated
more fully, together with the following:-
Friction. Rolling friction, brakes, holding power of coiled
ropes, slipping of a belt.
Strength of Materials. Transverse strain on timber bean, girders, cantilevers, deflection of beams. Combined bending and twisting; combined bending and crushing; struts.
